++tinita for highlighting the important difference between testing for definedness and testing for truth (see perlsyn#Truth-and-Falsehood).

But even with the correction I prefer my version. Readability is in the eye of the programmer, but the first high-level programming subject I took at Uni (in Pascal!) emphasised structured programming, and this has remained with me. I prefer a function to have a single exit point (at the end) where possible. In Perl this is not always optimum, so I’ve had to learn to be flexible. But when — as in this case — the structured version is as straightforward as the non-structured one, I prefer the former. YMMV.

As always in Perl, TMTOWTDI.
