But this implies a rather enormous overhead in calling a function,
doesn't it?

What I meant was that if you do the following, in sequence:

  a. Define function foo.
  b. Define function bar, that calls function foo.
  c. Undefine function foo

Now, if you call function bar, will you get a "undefined function"
exception? But if point 1. really is true, I'd expect you get a
"undefined name" execption or somesuch.
