Oh I see. After realizing that, I think I've got something working. It 
didn't turn out as beautiful as I'd hope and I had to use the nomatch 
rule. But it seems to work.

One thing though, the parser matches tokens in the string from right to 
left. For example, if I have the string, "A &1little&2 girl." and use LPC 
function calls when the &c tokens are matched, the &2 token will be 
matched before the &1 one. Since I want to build a state in the parser 
object while parsing, that can decide how the remainder of the string will 
be parsed, I would like if the matches were made in left to right order? 
This seems tricky to me, but I have to ask. Is there a way one could write 
the grammar rules to force matching to be made in the other direction?
