Overview

Converts

def m( a, b = 1, *c, d, e:, f: 1, **g, &blk ) end

To something like

def m( a, , , , ) blk = $post_args = arguments[1..-1] $kwargs = $post_args.pop a = ? $post_args.shift : 1 c = ? $post_args[0..-1] : [] d = $post_args.last e = $kwargs.delete(:e) f = $kwargs.delete(:f) || 1 g = $kwargs.except(:e, :f) end
