A nit: let's go with a name that doesn't have "new" as part of it.
Something like "lsort" or "xsort" or somesuch. (I don't suggest
"nsort" because 'n' as the first character has a special meaning in
Emacs Lisp, so I'd like to avoid confusion.)

Do you intend to present an implementation that replaces sort-on as
well?
And what about performance?
Thanks.
