in reply to User-Defined Sub, Passing a Single Argument?

Method 2 should have parens: my ($arg) = @_;

As for which style to use, it really doesn't matter, it is all a matter of personal taste and I have used all three (though typically one of the first two).

Update: Better phrasing, thanks kennethk

    You may want to update your phrasing; the choice of method doesn't really matter, but your comment sounds like the parentheses don't matter. The missing parentheses are a bug.
