The pseudo-variable proposal seems entirely horrible to me, and
indeed was not discussed at all. I can see all kinds of abuse
and very little gain from this syntactic vinegar :-)

The idea of the evaluation of the right hand side being tied
in semantically to the evaluation of the left hand side like
this seems quite nasty to me, a real confusion in the
fundamental semantics of assignment. Right now the semantics
attributes of assignment are purely inherited, and you really
want to keep things this way.

Maybe I missed something, but I did not see any significant
support for this particular notion, the discussion was almost
all about the much cleaner (though still fraught with
problems)+= type notation.

I consider a renaming to be much cleaner for a reader than
the use of your pseudo-variable (the latter is just syntactic
sugar/vinegar for the former presumably???)
