I never measured memory when I use asModule, since for me the
compilation time becomes quite small. Even the D grammar (the biggest
I tried with Pegged, about 200 rules, so an order of magnitude bigger
than your grammar) becomes a module in a few seconds, and my computer
is not top of the line.

Maybe you can try to inline it some? See
