You could hack something together that does this I guess. Dynamic loading
works pretty ok on unix, yet you need a working compiler set, some way to
specify the right libraries and stuff for the loaded parts.

Best would probably be to rewrite a bit and convert the switch statements
and contents to tables with char ranges and function pointers to the
actions (bit of a simplified description this). These then could be loaded
on runtime. Parser would then degenerate to a driver for these tables.

I guess it's doable but not with the time I have to spent on antlr atm (and
then I'm not even mentioning d*mn MSVC)

Cheers,

Ric
