How about it, Ralph?

I'm a little curious about this. I believe you said that you added a
command line option to moose to choose between unique and non-unique
modes; was this just to make it easier for you to develop the patch, or
are there benefits to using the old code when using non-unique modes?
Otherwise it seems like you could just switch to your new code exclusively
and give the parser two mode declarations. (Although... this would double
the code size for most users unnecessarily? Oh well, forget it then).

It would be nice if this was available too, even if it doesn't get checked
in immediately. lex and moose are both very handy :)
