No way. Waste of space for instructions to check the flag at the start and reset it at the end. Waste of CPU time. Divide by zero? Subroutine calls itself? Drive against the traffic flow on the freeway? Expected outcome: crash or other unwanted result. Simple: don't do that! Why bother checking? No self-respecting FORTRAN programmer would want to use recursion anyway. And mixed case in a variable name? Sheesh. -- http://mail.python.org/mailman/listinfo/python-list
