Despite your explanations elsewhere, I would suggest that is it dangerous, and even unethical(in the most minor, trivial sense of that term) for you to make that determination.
What the f*** is he prattling on about?I hear the time-sync'd chorus emote.
Well, think of it like the cold war. And the continuous escalation that was the primary result of it.
If you can determine some difference between the overall effect of my module by determining whether it was required or used, then maybe there is some action I can take within my module to make that same determination and so alter that effect. But then, if you can detect it, and I can alter it, maybe there is some mechanism that will allow me to alter it but not allow you to detect it.
Of course, it's inevitable, that if I start taking action dependant upon whether you can detect whether I was required or used, that you are going to look for a method of subverting my method of detection whether I was required or used.
But if my module renames perl5x.dll and substitutes itself in that namespace, then I can intercept your calls to pp_require() and, falsely, report failure to require, but the go on to install myself anyway.
That may not work identically to use in all cases, but it would stop Ovid from telling the difference between use and require in 87.243789100000000000001% of cases. And hey, that got to be worth the effort :)
