Need Help??

Seriously, what's wrong with a much easier approach like this?

It could be much easier to read:

if (not $FOO_HAS_BEEN_CALLED) {

... if it were instead:

unless ($FOO_HAS_BEEN_CALLED) {

Otherwise, it seems reasonable.

Now that you mention it, I usually handle this kind of bail-out conditional with a simple test at the top: `return if $foo_has_been_called;` [download] Then you don't have to indent the whole rest of the sub.	[reply] [d/l]
