The canonical logical language is Prolog. However, Idealised Prolog

Hi,
Are cool kids supposed to put the comma in front like this?
Some cool kids do, some cool kids don't. Some do both, depending on their
mood.
The advantage of a leading , is that now the comma's line up, and if

I argue the second form is what people usually want.

No, just a new version of Cabal, which will work with 6.4.x.

Hi,
to start off, I'm using ldap-haskell straight from its darcs
repo under GHC-6.4.1, and it works. Just not quite like I
want.
First, I can't make a static compile:
$ ghc --make prog.hs -o prog
works without a warning, while
$ ghc --make prog.hs -o prog -optl -static

There might be issues with tuples though, for example (1,2,) would be
