The most realistic implementation is one from Nobu in
[ruby-core:19947], which ignores default values for optional
arguments.

  p ->(a,b=1,c=4,d){}.parameters
  # => [[:req, :a], [:opt, :b], [:opt, :c], [:req, :d]]

If it's OK, I will approve the patch.  The only concern will be we
currently have no parameter information for C implemented methods with
variable argument.

  p method(:printf).parameters
  # => [[:rest]]
