Re^3: Why $File::Find::prune = 1 returns used only once error

because Perl knows not to complain about $File::Find::name for example.

Based only on the code in the root node, I get the "used only once" warnings for both $File::Find::prune and $File::Find::name. Are you sure you're not using the latter twice?

I tried removing the explicit 'find' from File::Find->import, made no difference

find is exported by default, so yes, it doesn't make a difference. If you didn't call import at all (the equivalent with use is "use File::Find ();"), then you'd have to call it as File::Find::find(). And BTW, the other difference between importing find() at runtime (e.g. require + ->import) vs. compile time (e.g. use) is that in the latter case, you could omit the parens on the find function call.

Lol, yes, I discovered this omitting the parens with use vs require, that's an issue that actually had made me give up initially on pulling the File::Find into a local require rather than a global use, that came about from using code I didn't understand copied from the interweb, but once I finally figured out why find was failing, I learned my lesson, and now do not omit parens even when I can with a few exceptions to keep things maintainable and readable.
