Re^3: Suppress 'Can't chdir to' warnings for File::Find

My gut on the performance hit is stats the item in question twice. I could be COMPLETELY wrong on that though.

There's a feature with `stat()` where it caches the item being tested on first call, to reduce overhead that would likely help reduce checking time. Note the `_` at the end of the one-liner below. That's the cached item. `perl -wMstrict -E 'say -f "utf.pl" && say -e _'` [download] Also, one could also look at the `no_chdir => 1` feature of File::Find, however I don't know if one would get different warnings in that case, or if it'd just fail silently and move along when it encountered a restricted dir.
