Day 9 and 10: Synopsis 6 mostly finished!

On Day 9 and Day 10 of Pugs, the combined productivity of Autrijus and Bestian has gone into full gear. We have implemented most of Synopsis 6:

• Formal parameters declaration and binding
• Invocant-based multimethod dispatch
• Optional(?), named(+ and ++), slurpy(*) parameter declaration and invocation
• Extraction of higher-order placeholder variables
• Proper semantics and extraction of @_, %_ and $_
• Defaulting of optional/named parameters that can reference to preceding parameters
• Global variables and subroutines: &*foo, $*bar
• Context propagation from types of formal parameters
• The "returns" / "is returns" trait

The code has been committed to the darcs repository (svn is currently offline). It broke the parenthesis parsing in parsec a bit, so I'll refrain from releasing 6.0.3 until that stabilizes.

Next in sight: Arity counting (&sub.arity), Currying (&sub.assuming), hiearchical types (Array of Array of Pair of Int), user-defined infix/circumfix operators, anonymous subroutines, and control structures. Stay tuned!
