Pardon me if this is a stupid/frequently asked question...
The GHC Prelude has some extensions to the Prelude in Haskell 98 or Haskell 2010. For instance, it has the Applicative type class, whose bindings overlap with some old code of mine. Where are these non-standard extensions documented? The Applicative class is documented at
https://downloads.haskell.org/~ghc/latest/docs/html/libraries/base-4.9.0.0/P...
but it's not picked out as something non-standard.
Do you mean that it's now in the Prelude as opposed to being in a different module? If so, that came through from the Applicative => Monad Proposal (aka AMP): https://wiki.haskell.org/Functor-Applicative-Monad_Proposal There's also the GHC migration guide that might be helpful: https://ghc.haskell.org/trac/ghc/wiki/Migration
I didn't find it documented where I would have expected in the GHC docs at
https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/bugs.html#ha...
Yes, that's a little odd.
nor did I see a way to get a standards-compliant prelude?
There's the haskell2010 (and also a haskell98) package: http://hackage.haskell.org/package/haskell2010 I'm not sure how well it works now though; AMP appears to have broken it: https://ghc.haskell.org/trac/ghc/ticket/9590 -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com http://IvanMiljenovic.wordpress.com
