And far more than that. The META class of parsers can be used to build
full top-down recursive-descent compiler-style parsers, very quickly and
easily. Somewhere back around 1971(?), I used the META2 compiler-compiler
on a DEC PDP-10 to build a toy BLISS compiler in a weekend. (Generated
*horribly* inefficient but correct code.) Great fun!
