Minor Fixes to Haskell 98
The following are minor departures from Haskell 98 that are already present in one or more implementations, even in compatibility mode, and considered by some to fix bugs in Haskell 98:
- NondecreasingIndentation (GHC, Hugs)
- QualifiedIdentifiers (partially GHC, Hugs, …?)
- LineCommentSyntax
- RecordPatternMatching
- FixityResolution
The following are minor fixes to Haskell'98 that are not available anywhere yet, because they break backwards compatibility. They exclude otherwise-valid H'98 programs, rather than admitting non-H'98 programs.
