Perhaps the name `sort-by' would be more consistent with the
`seq-sort-by' function defined in lisp/emacs-lisp/seq.el?

^^
Out of curiosity, is there a preference/convention
for/against `function'-quoting lambdas in the Emacs source
tree? The only reason I avoid it is because it breaks the
fontification of `lambda' as a macro. :)

^^^^^
Is this not the same as using plain `sort' here?
