Right, that's inconvenient.  Maybe prefix with them all with "q"?
("self" isn't a keyword fwiw.)

I don't see it in the docs, but the parser source code fesses up
thusly:

% grep keywords.insert parse.cxx
      keywords.insert("probe");
      keywords.insert("global");
      keywords.insert("function");
      keywords.insert("if");
      keywords.insert("else");
      keywords.insert("for");
      keywords.insert("foreach");
      keywords.insert("in");
      keywords.insert("limit");
      keywords.insert("return");
      keywords.insert("delete");
      keywords.insert("while");
      keywords.insert("break");
      keywords.insert("continue");
      keywords.insert("next");
      keywords.insert("string");
      keywords.insert("long");
      keywords.insert("try");
      keywords.insert("catch");
