Template Haskell seems to be type-checking some quasi-quotes, even when they
are not going to be used. This is of course a terrible nuisance, since it
means it can't be used to work around interface incompatibilities between
libraries for different versions of GHC (such as the recent change in

Still, in your cpp-like application, I guess your story is that the

such that bar was in scope. If the condition evaluates to False, then
bar really might not be available.

I have no idea what this is:

Hi,
if I try to supply a signatur for the local function showsl below,
then ghc rejects a constraint (Show a) whereas hugs (and nhc98) needs
this constraint.
What should be the correct notation? (apart from omitting any signature)
Cheers Christian

I've just noticed that I used ghc with -fglasgow-exts.
Without extensions hugs, ghc und nhc98 consistently need the constraint
in the type signature (below)
showsl :: Show a = List a - ShowS
Switching the extensions on, breaks this code, however (ghc only).

Greetings.
Say I have the following function, adapted from Pierce, Types and
Programming languages:
f n () = (n, f (n + 1))
Now, this function fails to typecheck in ghc 6.0.1 because the
subexpression f (n + 1) has the infinite type t = () - (t1, t)
And so I assume (perhaps wrongly?) that f

Does anyone know about documentation (preferably on the Web) on how to
prevent/find/remove space leaks?
Are there any differences between Hugs and GHC or any other Haskell platform,
regarding space leaks?
