Dear Committee,
the requested data (hackage and survey) is in, has been aggregated, cooked, seasoned and is ready for consumption. 116 extensions are waiting on your assessment, so time to vote!
## Procedure
Please vote by email to this list, in a response to this thread.
I want to make tallying easy and automatic, and my code will consider an extension Foo voted for if you write "Foo: yes" on its own line. This means you can include rationales, write "Foo: maybe" and "Foo: no" to remind yourself and others that about where you are, and you can safely quote other’s mails. For example, if you write:
---- begin example ----
Easy ones:
DeriveFooBar: yes OverloadedBen: no
These ones are tricky:
ImplicitExceptions: yes I know nobody likes that one, but I do.
RandomEvaluationOrder: maybe Not sure about this one, here is why…
Richard wrote: DependentHaskell: yes Rationale: See my thesis
I’m not convinced yet, tell me more, so DependentHaskell: maybe
---- end example ----
then you have voted for DeriveFooBar and ImplicitExceptions. Only “yes” matters, “no”, “maybe” and “later” are all ignored.
I will shortly send my first ballot around. Also see the end of this mail for a copy’n’paste template.
You can update your vote as often as you want. Please always send your full votes (I will only consider your latest email). I encourage you to do that early, e.g. maybe start with a mail where you list the obvious yes and nos, and keep some at maybe and then refine.
The timeline says first votes should be in within two weeks, and then a bit more to refine. But the earlier the merrier!
The quota is 8. In particular, if everyone votes (and I hope everyone will), an extension won’t make it this round if 4 don’t include it.
## Data
Please see
https://github.com/ghc-proposals/ghc-proposals/blob/ghc2021/proposals/0000-g... for the data, including explanations. It is intentionally not sorted by the data, as the choice of ranking function would already be quite influencing.
You may want to play around with that data, e.g. sort it by your own criteria etc. I looked long for an online service where I can upload the data and allow you to explore it, but then I noticed that that's a bit stupid, since we all probably can do it best with Haskell.
So I made it easy to load the data into GHCi, see the instructions at
https://github.com/nomeata/ghc-proposals-stats/blob/master/ext-stats/README.... which allow you, for example, to do this
*Main> mapM_ (\E{..} -> Text.Printf.printf "%s: %d\n" ext survey_no) $ take 10 $ reverse $ sortOn (\E{..} -> survey_no) (M.elems exts) AllowAmbiguousTypes: 195 CPP: 192 IncoherentInstances: 176 Arrows: 156 Strict: 153 ImplicitParams: 147 UndecidableInstances: 144 OverlappingInstances: 144 Unsafe: 139 TemplateHaskell: 137
Of course, if someone wants to upload the data somewhere and share that, that's also useful.
Let me know if some of this doesn't quite work for you, and should be improved. Maybe we need a web form instead of mails?
## PS: Blank ballot
To start, you could copy the following into an email
AllowAmbiguousTypes: maybe ApplicativeDo: maybe Arrows: maybe BangPatterns: maybe BinaryLiterals: maybe BlockArguments: maybe CApiFFI: maybe CPP: maybe CUSKs: maybe ConstrainedClassMethods: maybe ConstraintKinds: maybe DataKinds: maybe DatatypeContexts: maybe DefaultSignatures: maybe DeriveAnyClass: maybe DeriveDataTypeable: maybe DeriveFoldable: maybe DeriveFunctor: maybe DeriveGeneric: maybe DeriveLift: maybe DeriveTraversable: maybe DerivingStrategies: maybe DerivingVia: maybe DisambiguateRecordFields: maybe DuplicateRecordFields: maybe EmptyCase: maybe EmptyDataDecls: maybe EmptyDataDeriving: maybe ExistentialQuantification: maybe ExplicitForAll: maybe ExplicitNamespaces: maybe ExtendedDefaultRules: maybe FlexibleContexts: maybe FlexibleInstances: maybe ForeignFunctionInterface: maybe FunctionalDependencies: maybe GADTSyntax: maybe GADTs: maybe GHCForeignImportPrim: maybe GeneralisedNewtypeDeriving: maybe HexFloatLiterals: maybe ImplicitParams: maybe ImportQualifiedPost: maybe ImpredicativeTypes: maybe IncoherentInstances: maybe InstanceSigs: maybe InterruptibleFFI: maybe KindSignatures: maybe LambdaCase: maybe LexicalNegation: maybe LiberalTypeSynonyms: maybe LinearTypes: maybe MagicHash: maybe MonadComprehensions: maybe MonadFailDesugaring: maybe MonoLocalBinds: maybe MultiParamTypeClasses: maybe MultiWayIf: maybe NPlusKPatterns: maybe NamedFieldPuns: maybe NamedWildCards: maybe NegativeLiterals: maybe NoImplicitPrelude: maybe NoMonomorphismRestriction: maybe NoPatternGuards: maybe NoTraditionalRecordSyntax: maybe NondecreasingIndentation: maybe NullaryTypeClasses: maybe NumDecimals: maybe NumericUnderscores: maybe OverlappingInstances: maybe OverloadedLabels: maybe OverloadedLists: maybe OverloadedStrings: maybe PackageImports: maybe ParallelListComp: maybe PartialTypeSignatures: maybe PatternSynonyms: maybe PolyKinds: maybe PostfixOperators: maybe QualifiedDo: maybe QuantifiedConstraints: maybe QuasiQuotes: maybe RankNTypes: maybe RebindableSyntax: maybe RecordWildCards: maybe RecursiveDo: maybe RoleAnnotations: maybe Safe: maybe ScopedTypeVariables: maybe StandaloneDeriving: maybe StandaloneKindSignatures: maybe StarIsType: maybe StaticPointers: maybe Strict: maybe StrictData: maybe TemplateHaskell: maybe TemplateHaskellQuotes: maybe TransformListComp: maybe Trustworthy: maybe TupleSections: maybe TypeApplications: maybe TypeFamilies: maybe TypeFamilyDependencies: maybe TypeInType: maybe TypeOperators: maybe TypeSynonymInstances: maybe UnboxedSums: maybe UnboxedTuples: maybe UndecidableInstances: maybe UndecidableSuperClasses: maybe UnicodeSyntax: maybe UnliftedFFITypes: maybe UnliftedNewtypes: maybe Unsafe: maybe ViewPatterns: maybe
