I discovered a minor cosmetic bug today. After my
undescribable hapiness about the fact that GHCi now has the
:i command, I started playing around, and discovered the
following ugly output:
Prelude :i []
-- [] is a data constructor
[] :: forall t_12. [t_12]
Thanks, I've fixed
Thanks for your help Simon.
Unfortunately I think I have spent enough time on this, and not enough
on what I would like it for, without getting there - I may try again in
the future if the porting process becomes better documented/tested.

The following code works...

hello,
Does anybody know why it is not possible to define the folowing function
in ghc?
= \x y - (x+y - length [1..(gcd x y)] = round ((x+1)/2)) )

I'm curious why the following code is invalid (from a language design
point of view):

foo [] =
foo = snd . head
ghc complains:

I don't understand why this should be invalid? Basically, as I read

I'm not sure. I actually prefer it written out so that the number of
arguments in the cases matches (as GHC enforces).

The Vim syntax file for literate Haskell programs handles code lines that
begin with a '' character fine. But in GHC much of the code is defined
between \begin{code} and \end{code} pairs, and that shows up as one
giant comment.

It should actually be close to being at the state where I just have to add

can, the arrow keys.
