liblong-jump-perl binary package in Ubuntu Lunar amd64

 Long::Jump essentially provides a multi-level return. 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.
