Yes, I've used my blurry version of *algorithmically faster*, which
means iterating on one list instead of two in succession; the
complexity is the same, of course.

By preloaded files, do you mean the ones on `preloaded-file-list'?
There are 112 files in this list on my system, so it's quite a large
restriction. Is it no-more, no-less, i.e. only these 112 files?

Maybe the byte compiler could do some linting to enforce this
restriction?  It already contains a lot of checks.
