Thanks Carter! I have just asked basically about it on Reddit, in the announce thread. I'll give it a spin, and if it works I will share the link (if you are ok with that!) on the same Reddit post. Alfredo On Tuesday, 23 December 2014, Carter Schonwald wrote:

============================================================== The (Interactive) Glasgow Haskell Compiler -- version 7.8.4 ==============================================================

The GHC Team is pleased to announce a new patchlevel release of GHC, 7.8.4.

This is an important bugfix release relative to 7.8.3 (with over 30 defects fixed), so we highly recommend upgrading from the previous 7.8 releases.

The full release notes are here:

https://downloads.haskell.org/~ghc/7.8.4/docs/html/users_guide/release-7-8-4...

How to get it ~~~~~~~~~~~~~

The easy way is to go to the web page, which should be self-explanatory:

https://www.haskell.org/ghc/

We supply binary builds in the native package format for many platforms, and the source distribution is available from the same place.

Packages will appear as they are built - if the package for your system isn't available yet, please try again later.

Background ~~~~~~~~~~

Haskell is a standard lazy functional programming language.

GHC is a state-of-the-art programming suite for Haskell. Included is an optimising compiler generating good code for a variety of platforms, together with an interactive system for convenient, quick development. The distribution includes space and time profiling facilities, a large collection of libraries, and support for various language extensions, including concurrency, exceptions, and foreign language interfaces (C, whatever). GHC is distributed under a BSD-style open source license.

A wide variety of Haskell related resources (tutorials, libraries, specifications, documentation, compilers, interpreters, references, contact information, links to research groups) are available from the Haskell home page (see below).

On-line GHC-related resources ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Relevant URLs on the World-Wide Web:

GHC home page http://www.haskell.org/ghc/ GHC developers' home page http://ghc.haskell.org/trac/ghc/ Haskell home page http://www.haskell.org/

Supported Platforms ~~~~~~~~~~~~~~~~~~~

The list of platforms we support, and the people responsible for them, is here:

http://ghc.haskell.org/trac/ghc/wiki/Platforms http://ghc.haskell.org/trac/ghc/wiki/CodeOwners

Ports to other platforms are possible with varying degrees of difficulty. The Building Guide describes how to go about porting to a new platform:

http://ghc.haskell.org/trac/ghc/wiki/Building

Developers ~~~~~~~~~~

We welcome new contributors. Instructions on accessing our source code repository, and getting started with hacking on GHC, are available from the GHC's developer's site run by Trac:

http://ghc.haskell.org/trac/ghc/

Mailing lists ~~~~~~~~~~~~~

We run mailing lists for GHC users and bug reports; to subscribe, use the web interfaces at

http://www.haskell.org/mailman/listinfo/glasgow-haskell-users http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs

There are several other haskell and ghc-related mailing lists on www.haskell.org; for the full list, see

http://www.haskell.org/mailman/listinfo/

Some GHC developers hang out on #haskell on IRC, too:
