#1 Fixed Implicit parameters cause strange behavi nobody nobody
Description
ghc-5.00.1 (with glasgow-exts) compiles the following
program:

> foo :: ((?x :: Int) => b) -> Int -> b
> foo s z = s with ?x = z
> main = foo (print ?x) 42

Running the generated code prints nothing. (No output
is produced
even if we add putStr "Hello world\n" before the call
to foo).
#2 Fixed rewrite rules, forall, no -fglasgow-exts simonmar nobody
Description
Using rewrite rules without specifying -fglasgow-exts
results in (e.g.) the following error message:

SList.hs:59: parse error on input `.'

i.e. the . in "forall vars . rule".

Manuel (chak@cse.unsw.edu.au) tells me this is a
parsing problem.
#3 Fixed DiffArray should be instance of Show nobody magunter
Description
I would think that DiffArray should be an instance of
Show.  It's not.

   thanks,
