No, it was just a course exercise. I've used it once or twice to
describe some grammars I've created, but it's not really been used for
anything practical in the real world. In particular, I've never gotten
around to defining a syntax for the semantic actions section (which has
been left as an "ad-hoc" item in HyGram), I've never created a "parser
generator" for HyGram (which is what it would be really useful for),
and I've never bothered pushing HyGram as an alternative to EBNF. As
such, it's pretty much languished.
