Um, goto &SUB does create a new stack frame, but only after the old one is stripped off. (Shouldn't leak memory though.)

And goto LABEL doesn't do a linear search through the source file. And the way the (non-linear) search is written, going from the last statement to a label at the beginning should be pretty fast. Benchmarks are the only way to tell which will be faster.
