in thread compare arrays, and list the difference

BrowserUk:

It seems that "How do I compute the difference of two arrays? How do I compute the intersection of two arrays?" gives the essential information. Perhaps my expectation that it's a simple step from the FAQ to this question is a bit much?

In any case, since it's not an exact match to the question, I shouldn't have said that it's a FAQ.

When your only tool is a hammer, all problems look like your thumb.

[1nickt]: marioroy Yes, I am using it with MCE, as is Discipulus I believe. I was trying to work out how to make a cpanfile that would be smart enough to know which deps to require.
[1nickt]: See this code. (I expected to simply eval loading threads as a check, but weirdness happened with Perlbrew so it's a grep of -V ...)
[choroba]: Config might be better than grepping -V
[Corion]: Also see Config::V, which is less of that hackery, or that hackery hidden in a module ;)
