[Haskell-cafe] Backward compatibility

[Stephen Tetley]

Hi Adrian

I don't want to argue against your rant for the sake of it, but
Haskell is a fairly conservative language. The Glasgow Haskell
Compiler supports it's own dialect "Glasgow Haskell" which is fast
moving, but the developers of GHC do work hard to maintain
compatibility with standard Haskell 98 and Haskell 2010 (optionally
enabled with compiler flags). Afterall Haskell now is fairly widely
used as a teaching language which befits stability as course
textbooks, lecture plans etc. can't be in hock to a language that
changes every year.

Best wishes

Stephen
