You've piqued my interest, since I'm the first to admit that my grammar 
specifications are hard to read.

Where do you put the action in the above code?

classmethod :
	access_specifier
	method_type_specifier
	method_return_type_specifier
	method_declaration
	method_body
	{ doSomething(); }

What if there's more than one reduction possible?

classmethod :
	access_specifier
	method_type_specifier
	method_return_type_specifier
	method_declaration
	method_body
         { doSomething(); }
      |  something_else
	another_thing
	even_more
	blah_blah
	{ doSomethingElse(); }

This looks like it's getting hard to read.

Agreed!  I wish that more languages allowed hyphen use in identifiers. 
Dylan is the only one I can think of off the top of my head.
