You can mark a spot with +setjump() and then unwind the stack back to that point from any nested stack +frame by name using longjump(). You can also provide a list of return values. + +This is not quite a match for C's long jump, but it is "close enough". It is +safer than C's jump in that it only lets you escape frames by going up the +stack, you cannot jump in other ways. + +WWW: https://metacpan.org/release/Long-Jump |
