Is there a way to return a method parameter names in ruby [duplicate]

If you are on Ruby 1.9.1 you can use the MethoPara gem. This allows you to do the following:

def method_called(arg1, arg2)
  method(caller[0][/`([^']*)'/, 1].to_sym).parameters
end

You can use the approach proposed by Michael Grosser at his blog.
