Hi,

1.9 has Proc#parameters:

Proc.new { |a,b,c| }.parameters
# => [[:opt, :a, nil], [:opt, :b, nil], [:opt, :c, nil]]

which means all a, b, c are optional, and their default values are
nil.

perfect! that tree would be fantastic, would it be reasonably possible
to backport as a gem extension? Im not sure what would be involved, or
if to many changes would have to be made.

Thanks matz

only been using it for about 2 or 3 months, but I love it, has changed
my perspective on programming thats for sure. Nice to actually enjoy
what I do again :)
