I had wondered that myself, but I don't think it is.  Schwern's question
was how could you determine if it is the same code, not the same function.
If you replaced bar() with $bar->(), then it would be an instance of the
halting problem.  In that case, to prove that the functions referenced were
identical, you would have to run them.
