Hi,
Has anyone managed to get cabal to run on Windows? I'm running Windows
XP. There are lots of other things, including old version of Haskell
tools, installed, but it's too costly to try installing cabal on a fresh
machine image.
Whenever I do cabal update, the response is Unsuccessful
serious. Since
[t|t-ts] and other forms are gone, I've come to think of the syntax [foobar|
as already taken for all foobar.
The loss here seems minimal but the gain is that DSLs can look more natural.

its own documentation
files. This is usful in a GUI program, for example, where it's nice to
make the documentation availble under the Help menu.
Something along these lines (with a cleaner design) would be generally
useful.

Hi,
I would like to use the API for ghc, so that a running program can load
a module (Foo.o) and use a function defined in that module. From the
documentation available, it seems like thatś possible, but I can´t
figure out how to do it. There is an example on the wiki, but the
explanation
on the main platforms (including Macintosh - has that
been tested?). If ghc tries to support both readline and editline, along
with haskeline, applications written in Haskell will have different behaviours
depending on the combination (platform,line-editor). Better just to simplify.

but according to gcc documentation -V requires an argument.
Has anyone managed to get hs-plugins to work? If so, what platform,
which version of ghc and gcc, and where did you find the hs-plugins
source?
Best wishes,

gcc version 4.3.0 20080428 (Red Hat 4.3.0-8
years ago, but it's never
worked on any of my systems since then.

approach observable sharing instead of pointer equality.

reka steps, but the
transformational approach may make it possible to automate the
boring steps while allowing the programmer to insert clever
insights. You can't do this with compilers, and you can't do
it with languages that can express algorithms only at one level
of abstract
algebraic laws.
There need to be several flavors of complex numbers, since there are two
orthogonal issues: (1) how to represent the complex itself (real+imaginary,
polar representation etc.), and (2) what underlying type is used for the
components (Float, Double, Rational, Real etc.)
