No this doesn't help. You're still paying the cost of a function call. And function calls are s-l-o-w in Perl.

I recently encountered a program of which 20% of the run time was being absorbed by a debug() that was being called to do nothing. (postgrey, in case you were wondering).

My solution was to change the code to

debug("foo") if DEBUG;

... but only because I was worried about performance. From a readability point of view, it sucks.

True macros would be a nice addition to Perl. I know that there's a Macro module that purports to do just this, but I have never used it.
