There are a couple of things you can do:

	* The "right" way would be to modify the grammar, but this could
	  be prohibitive.

	* The easy way is that whenever you see something you are
	  interested in (for example inline comments), you track those,
	  and keep them around in a variable in the tokenizer that you
 	  can later query from the parser, just like we do with the 
	  value of the token.
