When looking around on the web, I've seen a few sites where they mention the
"other" rename, but no one seems to use it very much. One person even
mentioned it as "pretty useless" or something like that…

I don't know very much about Perl, almost nothing at all, but isn't Perl a
programming language that doesn't use a compiler? Maybe I misunderstood, but
isn't the Perl rename thing written in Perl? If so, shouldn't that mean that
rename is quite a lot slower than it would be if it was written in, for
example, C, like I think the rest of the Unix/GNU/Linux commands are, such
as mv?

That's why I asked for a solution without involving rename at all. Not that
it matters if renaming a few hundred files recursively in a folder with, in
my case about 21500 objects (files, links and folders), but I always think
that if I can make something faster, I should, at least if it doesn't take
too much time… In this case I learn something on the way, which I take as a
valuable bonus.
