perl-Long-Jump - Mechanism for returning to a specific point from a deeply nested stack
- Description:
This Perl module 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. It is safer than C language jump in that it only lets you
escape frames by going up the stack, you cannot jump in other ways.
