[Haskell] ANNOUNCE: jhc 0.7.7 is out.

[John Meacham]

Announcing jhc 0.7.7! This release fixes a large number of bugs that cropped up
when compiling haskell out in the wild as well as adds some more features. A
major one being the garbage collector is enabled by default.

 http://repetae.net/computer/jhc/

Changes: (including some changes from the unannounced 0.7.6 release)

* The Garbage Collector is now enabled by default.
* new standard libraries
    * transformers
    * parsec
    * QuickCheck
* report proper errors with line numbers for various issues with compiled code.
* New option '-C' that compiles to C code and stops, useful for targeting other
  platforms or building shared libraries.
* Nintendo Wii added as target (thanks to Korcan Hussein)
* Fix major performance bug that kept WRAPPERs from being inlined in
certain places.
* Typechecking speed greatly increased.
* monomorphism-restriction flag is now respected
* empty class contexts now work
* unicode in haskell source supported now
* Type Defaulting now works properly
* RULES parse like ghc now for compatibility
* 'do' 'where' on same indent now parses
* Build system fixes and cleanups
* irrefutable lambda pattern bindings desugar properly now.
* GHC parsing regression tests have been ported to jhc, helped find
and fix many bugs.
* Certain optimizations would discard RULES, these have been fixed.
* Removed quadratic behavior in optimizer, speeds things up noticibly.
* Garbage collector improvements, caches are pre-initialized.
* Fix shiftL/R implementations for built in types.
* All Num, Real, and Integral magic removed from compiler. This is a very
  good thing.
* improved help messages

Awesome :) you mentioned transformers package, did you have a look at the issues I had with using monad transformers with monad stack containing IO? I posted it a few weeks ago here: http://www.haskell.org/pipermail/jhc/2011-January/000862.html

Greetings!

A few questions about the inclusion of parsec:

1. It is parsec-2, not parsec-3, right?

2. Does this change consist of merely inclusion parsec as a standard
library, or are there any compiler improvements in this release that
made it possible to build parsec?

Don't worry what people think, they don't do it very often.

Yes, it is parsec-2. 2.1.0.1 to be exact.

There have been a lot of bug fixes and improvements in this version, I can't
remember if any were particularly enabling for parsec or not. I wouldn't be
surprised if it didn't work well before this or the last release.
