While this adds yet another attribute to the built-in/implemented-as-built-in/
special-built-in zoo of utilities, I tend to like the concept.

So for the $1="a b" case, this makes
foo=$1
behave diffently from
local foo=$1
and
export foo=$1
. Of course one could argue (and I would expect KRE to argue that way) that
yes, that's the way sh works, and everyone In The Know would expect this, and
assign foo=$1
would also behave that way no matter how "assign" is defined (well, I would't
bet KRE couldn't make up a definition that makes it work the assignment way,
but I myself can't).
Another point is that That GNU Monstrosity behaves the way I would (sorry)
have expected.

Depending on your mindset, it would follow POLA.
