Alternatives are not supported at the function header level. You get the
parse error because it thinks they are function calls. The solution is to
have one rule r that matches the functions you don't want, and marks the
function names with a position variable. Then have another rule that
matches any function but declares a position variable
position p != r.p;
which it then uses to be sure that the name of the function is not in one
of the positions collected by the first rule.
I can give more detail if it is not clear.
