You misunderstand me. My quibble isn't over the exact syntax (in fact,
I completely agree about the superiority of the proposed ordering),
but rather that we're introducing syntax to do something that can
already be done with a function (nested()) and is /extremely/ similar
to another case (parallel for-loop) where we are opting to still
require the use of a function (zip()). This proposed asymmetry

This parallel does quell my concern somewhat.
