Re your second question, here's a question (rhetorical as well as didactic, as we'll soon see):
"Why not try it?"

Now, that would be terrible advice if your program were invoking rm * or del *.* /FQ or drop tables LIKE *.

But, it isn't.

Many, many newcomers to perl seem to fear the empirical method of obtaining answers to such questions as "does $count{word}++ do...?"

It's OK. But know that your computer won't belch "blue flames" (as one infamous poster asserted Perl had caused his to do) nor will a cautiously written test have you looking at a BSOD or kernel crash...nor will doing so cause your taxes to go up or your dog to run away. So, go ahead and try it.

PS: the answer is "no."
