No, I don't see this as an ethical problem.  This is where we draw the
distinction between "an idea" and "the expression of an idea". In my
opinion, a YACC grammar leans more towards an idea, rather than an
expression thereof (after all, a grammar is not just a matter of opinion).

If you feel uncomfortable with this, I'm sure you can type it in and then
inside vi, do ":%s/\<\([a-zA-Z]\)/my_&/g".
