FWIW, I also fail to see why let wouldn't be equivalent for most
intensive porpoises, but then I wouldn't trust myself to tell a porpoise
from a dolphin.

Surely rewriting in terms of let increases Hamming distance? ;)
In any case, my vote is for correct and simpler code over a smaller
diff.

AFAICT it's redundant because let always unwinds its temporary bindings,
in contrast with the previous add-function and setq which make permanent
modifications that require manual unwinding.
