in thread How to exit subroutine and go to Beginning of CGI Script?

One method is to make the "main" part of your code into a subroutine itself such that to start at the beginning again, you simply call that routine.

This will lead to memory exhaustion under some circumstances.

Question: is tail-recursion possible in Perl?

    It could lead to memory exhaustion. But then there's always goto &main; (or more likely @_=(); goto &main;). This form of goto isn't quite as evil as goto LABEL or goto EXPR.

    P.S. Of course tail-recursion is possible, though not always desirable :)
