Issue 92 - November 08, 2008
---------------------------------------------------------------------------
GHC version 6.10.1. Ian Lynagh [2]announced the release of [3]GHC
version 6.10.1! This new major release features a number of significant
changes, including wild-card patterns, punning, and field
disambiguation in record syntax; generalised quasi-quotes; generalised
SQL-like list comprehensions; view patterns; a complete
reimplementation of type families; parallel garbage collection; a new
extensible exception framework; a more user-friendly API; included Data
Parallel Haskell (DPH); and more! See [4]the full release notes for
more information.
Were it not for this message, I might never have noticed! :-}
(Presumably the main "announcement" was on one of the other Haskell
lists...)
Anyway, I don't see it anywhere in the release notes, but I get the vibe
that type families are supposed to be "fully working" now. Is that
correct? If so, why no mention anywhere?
Also, the release notes tantelisingly hint that the long-awaited
parallel-array stuff is finally working in this release, but I can't
find any actual description of how to use it. All the DPH stuff seems on
the wiki was last updated many months ago. You would have thought that
such a big deal would be well-documented. It must have taken enough
effort to get it to work! You'd think somebody would want to shout about
it...
