Ok (and I understand your arguments).

Hm, I do prefer using require_relative over require + $LOAD_PATH
changes; it looks cleaner to me and doesn=E2=80=99t touch shared
globals, but I guess that=E2=80=99s more of a personal preference.

What I was trying to ask is whether there couldn=E2=80=99t be
a Kernel#autoload_relative call or a =E2=80=98relative: true=E2=80=99
optional parameter to Kernel#autoload to make it symmetric
with the require/require_relative combination. I understand
your answer would be =E2=80=98there=E2=80=99s no need=E2=80=99. :)

Fully agreed; fixed in the quotation above
(I shouldn=E2=80=99t post before my morning coffee).
