Multiple iterations of dirEntries can produce different results, which
may or may not be what your program will be happy with.
Sticking an .array at the end will iterate a single time and maintain
the list forever because .array returns an array. :)
auto entries = dirEntries(/* ... */).array;
I'd be cautious of that. I don't know what the underlying code uses, it
may reuse buffers for e.g. filenames to avoid allocation.
If you are confident the directory contents won't change in that
split-second, then I think iterating twice is fine.
