A function decorator that rewrites the bytecode to enable goto in Python

Is that faster than (or comparable to) raising an Error in the inner loop and catching it outside the outer loop?

Internal error bubbling code is slow and can change from release to release. And it's definitely not intended for the job.

probably faster since it was built for this purpose, throwing an error would have to at least create an exception object, then create stack trace and the other setup stuff.

As i said I code for almost 20 years and I only had to use it once so far, but people that maybe work a lot more with stuff that needs a lot of performance might use it much more often.
