Yes you can do so, but you once again get the same polymorphism
problem:
1) If for is used polymorphically in the body of f you're dead.
2) true_f will be monomorphic as well, unless you eta-expand it as in:
   let true_f () = f for ()

PS: for is indeed a keyword, and this identifier cannot be used as a
regular argument or function name ...
