C needed a different keyword to avoid needing lookahead, since 'if (foo);
else' could either be part of an if statement or an if statement followed
by an 'else:' label otherwise. That's not fundamentally a problem for us.
'default' is interesting as an identifier name in general so I think it's
worth considering giving it back.
