This will allways call the Debug() sub. The overhead may or may not be a problem in your production systems, it all depends on how many times this call is executed.

Imagine a few thousand times per minute. (Or per second...)

I propose the alternative solution: 

$debug=1;
$debug&&print("Debug info...\n");

The above should require less overhead. I've even read somewhere that Perl optimizes this so that the $debug&& doesn't have to evaluated, but unfortunately I can't find back the reference to that text. :-( Maybe some of the well educated Monks may chime in about that?

If there is no reason to change the value of $debug during execution, the following should be even smarter(?): 
*DEBUG=\1;
$DEBUG&&print("Debug info...\n");
