Rename RecordPuns extension to NamedFieldPuns
The NamedFieldPuns
has been around for ages. It's in the original Cabal design spec in the extension list. It was implemented in nhc98 for yonks (with the flag -puns
). In older ghc it was enables with -frecord-puns
.
In ghc-6.8 we split up the -fglasgow-exts
flag into lots of separate named extensions. We added an extension RecordPuns
for the thing that -frecord-puns
had enabled previously not realising that there was already an older name for the same thing, namely NamedFieldPuns
.
So I propose that ghc moves to using the standard extension NamedFieldPuns
and keeps RecordPuns
as a deprecated alias for NamedFieldPuns
. Cabal can fix things up so that for ghc-6.8 it maps the NamedFieldPuns
extension to -frecord-puns
or -XRecordPuns
.
The moral of the story here is that all the extensions in Language.Haskell.Extensions should be well documented in that module. For one thing that'd serve as a useful reference for users, but also for compiler hackers to pick consistent names for the same concepts between implementations.
