It seems a while since we had any news of recent ghc developments.
For those of us who're not following the cvs archive, could the
maintainers give us a brief summary of recent progress on the ghc-hugs
"marriage" and other recent ghc work?
Thanks, Jens
Plus ca change...
I advocated overloaded array operations in similar manner some years
back among pH enthusiasts---this being years before functional
dependencies, though, the multiparameter type classes worked only in
the pH compiler. :-) (I recall audible complaints from Simon P-J among
others.

Oh, thanks. As you can see, I've been through a few iterations with the
design already :)

You're right of course that arrays are quite expensive, but

How can I build fptools suite on system without Haskell installed ?
(I'm using Linux-x86 system but prefer to compile everything myself).
I've build ghc configured with --enable-hc-boot; but when I try to
configure it without this switch to build the hi files (as described
in the manual), I get m

I'd like to solicit some comments on the following proposal for generalising
GHC's various array mechanisms.
The aims are twofold:
- make it really easy to replace an existing
(immutable) Array with a strict unboxed
array type (i.e. just by changing the type
