Well, any time you have a do-block like this you're using failable
patterns:

That does not invoke fail.
Let's take a simpler example: do { x - Nothing; stmt }. This translates to
let
ok x = do { stmt }
ok _ = fail ...
in Nothing = ok
By the definition of (=) for Maybe, 'ok' is never called.

I don't see this one, although the junit option is there:
Argh! I made the release from the wrong branch. I've uploaded v0.3.1
and double-checked that it contains the right functionality.
Thanks for the heads-up!

An easier way of demonstrating this issue:

[3,7,11,15,19]
Prelude [3,7..22]::[Double]

What counts as unfailable?
(x,y) probably, but what about
data Foo = Foo x y
If we don't allow it, we add 'magic' to tuples, which is a bad thing, if
we do allow it, there are some odd consequences.

Hi, Cafe!
(This post got rather long, and in writing it, I probably answered
some of my own questions. I'll still post it because it might be
interesting to read for somebody).
This post concerns the currently central problem in Combinatorrent.
But the problem is interesting from another angle.
Building from source alone didn't help, but building from source
together with the following extra lines to .cabal/config worked:
extra-lib-dirs: /usr/lib
extra-lib-dirs: /opt/local/lib
This is not an ideal solution because this means that any OS X library
will shadow the corresponding Macports
Hi all,
I am using vacuum-opengl and vacuum-ubigraph to visualise and analyse some
of my data structures. They are quite helpful most of the time, however
sometimes I feel the need to tweak the generated output -- such as removing
the auto-generted identifiers from constrcutor names, pack some
Hi all,
I'm happy to announce the second major release of Hamlet[1]. Hamlet is a
HTML templating library which works via quasi-quoting, giving you
compile-time assurances, type safety and very efficient HTML generation.
I wrote a blog post[2] describing the changes in this version of Hamlet. The

In fact, the time you'd spend writing read instances would not compare to the
half hour required to learn parsec.
And your parser will be efficient (at least, according to the guys from the
parser team ;-)
