Changeset 12924 for src/Pugs/AST.hs

Message:

* Basic support for parsing Signatures with :().

Only named parameters are parsed, and optionals (incorrectly)
require a '?' even if they have a default value. No parameter
decoration (type constraints, access traits, etc.) is supported
yet. The following forms do work:

:($x:)
:($x)
:($x: $y, $z)
:($x: $y, $z? = 42)
:($x: $y?, $z) # correctly raises a parse error
