RE: should -fglasgow-exts support Haskell98?

No, -fglasgow-exts nukes some valid H98 programs.  Reason: the
extensions need to take up some extra syntax.  For example, 'forall' is
a keyword in -fglasgow-exts but not in H98.  

In your case it thinks you are write an unboxed tuple
        (# foo, baz #)

| I don't know if "ghc -fglasgow-exts" should always accept valid
| Haskell 98 programs.  If that is the intention, then here is a bug:
|    The following program is legal Haskell98 (works fine w/ "ghc") but
|    gives a parse error with "-fglasgow-exts":
| 
|    let _ #>> _ = 1 in (#>>)
| 
| Thanks.
| 
| BTW, I've just noticed that the ":t" command in ghci now gives me some
| very useful information for values without type signatures (when they
| are in a binding group in which other values have signatures): the
names
| of quantified type variables are nabbed from the other signatures.
| This is really nice!
