bug#45056: 28.0.50; lexical-let doesn't work with returned closures on nativecomp

[Mark A. Hershberger]

I just spent some time attempting to create a minimal test case using a
new user and some stripped down init.el, but couldn't reproduce it.

For now, I'm going to have to assume that the problem I'm seeing with
the lexical-let is a side-effect of some other problems my nativecomp
emacs is exhibiting (use-packages are acting funny).
