[project @ 1999-01-14 17:58:41 by sof]
Assorted minor Haskell 98 changes:
* Maximal munch rule for "--" comments
* _ as lower-case letter, "_" is a reserved id. Prefixing unused
variable names in patterns with '_' causes the renamer not to
report such names as being unused.
* allow empty decls
* comprehensions are now list comprehensions, not monadic.
* use Monad.fail to signal pattern matching errors within
do expressions.
* remove record punning.
* empty contexts are now legal (go wild!)
* allow records with no fields
* allow newtypes with a labelled field
* default default is now (Integer, Double)
* turn off defaulting mechanism for args & res to a _ccall_.
* allow LHSs of the form (a -.- b) x = ...
* Main.main can now have type (IO a)
* nuked Void (and its use in the compiler sources.)
* deriving machinery for Enum now also generate 'succ' and 'pred'
method bindings.
