transformers 0.4: change in accessor function exports?
by Michael Snoyman 07 May '14

07 May '14

One of the changes[1] in transformers 0.4 is as follows: 0.3: newtype Identity a = Identity { runIdentity :: a } 0.4: newtype Identity a = Identity a runIdentity (Identity x) = x While this may seem benign, I've already seen three cases where this caused breakage[2][3][4]. Is there a reason for this change in 0.4? If not, I'd like to request moving back to the previous formulation to avoid unnecessary breakage.

RFC: include a cabal-install executable in future GHC releases
by Carter Schonwald 04 May '14

04 May '14

Hey everyone, I'd like to propose that GHC releases 7.8.1 onwards include a cabal-install (aka cabal) executable, but not include the library deps of cabal-install that aren't already distributed with ghc.(unless ghc should have those deps baked in, which theres very very good reasons not to do.). currently if someone wants just a basic haskell install of the freshest ghc they have to install a ghc bindist, then do a boostrap build of cabal-install by hand (if they want to actually get anything done :) ). This is not a human friendly situation for folks who are new to haskell tooling, but want to try out haskell dev on a server style vm or the like! point being: It'd be great for haskell usability (and egads amounts of config time, even by seasoned users) the ghc bindists / installers included a cabal-install binary thoughts? -Carter
