|I wasn't sure about the evaluation happening in the right order, but I tested it and it seems to work. :)
Well, I would be inclined to worry about that too, and unless I find the bit of perl documentation that actually spells out the "official policy" about evaluation order for arguments in a subroutine call, I would consider a successful run on my own machine to be no guarantee that it'll work on other machines, or on my machine after I upgrade to the next Perl release.
And rather than take the time to hunt down that (possibly obscure) snippet of documentation, it would be easier for me just to add one more line of code and one more variable, so I don't have to worry about it.
