You shouldn't return delegates to nested functions, just like you 
shouldn't return pointers to local variables.
Delegates to nested functions contain a pointer to the stack frame of 
the enclosing function. If that function has returned, the stack frame 
may be corrupted (especially if you have called another function, like 
apply(), since then).
