Parse methods with splat params

Apparently this can come anywhere in the list of arguments, not just at
the end. See: http://endofline.wordpress.com/2011/01/21/the-strange-ruby-splat/
Parse methods with a proc parameter
Parse < and > as call expressions

Quite the oversight! Probably missed this because the other comparable
methods felt "more difficult" to parse, even though this is clearly
difficult because < plays double duty for inheritance.

Just discovered that this is **also** a method on Modules. You can use
this to determine if a Module is a subclass of another, or exactly equal.
