The paranthesis makes it pass the strict test. I guess strict figures that if you use paranthesis, you know what you are doing. It only detects barewords outside of curlies and not in front of the => operator, if I recall correctly. And if it finds one, it checks if it knows about any such sub (but it only checks backwards in the script). Thus, many place their main code last, after all the subs to be sure, and others (like me) place it first, and use &sub, which I think is the best. But I am drifting...

Here are some examples on what passes strict and not:

#!/usr/bin/perl -w use strict; # With a subroutine defined: foo(); # Prints "Stuff" &foo; # This too. foo; # Blows up, no such sub... yet. sub foo { print "Stuff\n"; } foo; # Is also ok, prints "Stuff" # With no subroutine defined: bar(); # Compiles, blows up at runtime *if* executed &bar; # This one too bar; # Blows up at compile time
So what has happened is that your solid code has not ever been evaluated to false... yet. ;-)
You have moved into a dark place.
It is pitch black. You are likely to be eaten by a grue.
