( For the vast masses downvoting this, BTW, please explain why the OP post is exemplifying good software design... think about it... not writing maintainable working code and falling for these kind of traps is what gives Perl programmers a bad name .. and this is *not* helping. I don't mind taking the hit here, go ahead, please stand up for your right to write broken code and drag down Perl in your workplace, etc. )
If you ever used the reason why it works for other things, it's fairly obvious. I remember seeing &sub($a,$b), sub( $a, $b ) and sub $a, $b, which are all the same for the most part, but are different formats. It was really unclear when people nested paren'-less subs. But as I got more experienced, as a programmer.. as a perl developer.. things got clearer. So the mistake in the program made me wonder, ok, this doesn't work, i know WHY it shouldn't work, lemme do some examples on paper using the logical error.

But I don't think you got downvoted solely for your opinion, 'cause to some degree, you are right, it could be clearer, but then again, $a||='bob' is too, eh?
