But again, this is only hidden stuff right?

So a stream like:

HIDDEN_COMMENT EOL_FOR_PARSER SOME_THING

getText() 
{
	// When called for SOME_THING this is always null as EOL_FOR_PARSER is
not hidden...
	while((curr=getHiddenBefore())!=null)
	{
		ret = curr.getText() + ret; // i know i know, slow.
	}
}
