Proc params extension

[Tj Holowaychuk]

Basically what I need is:

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

I was looking into creating a C extension.. but yikes the closure
portion is far beyond my limited C skills (lack of). Any ideas? is this
even really possible with the way evaluation is performed?

1.9 has Proc#parameters:

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

ps. I know you get this all the time, but thanks for Ruby man! I have
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
