Have you actually tried to implement that in your parser?

I am not asking because I want to be pedantic, but rather because this
is usually where parsing context-free languages becomes an enormous
error-prone mess, and is the reason why we have tools like lex/flex
and yacc/bison which take care of constructing the parser associated
to a set of productions on your behalf.
