The gist of it is the user wrote =+ instead of +=. I wonder if we
should disallow during tokenization the sequence "=", "+",
whitespace. Surely it's not a formatting anyone would aim for, but
instead a misspelling of +=.

Actually, I may have misunderstood the suggestion. I do _not_ think that
we should require that someone who writes code like
a=+b;
should be forced to put whitespace in their code, as ugly as it arguably
is that they don't (which is what I thought was being suggested).
However, if they've written their code like
a =+ b;
then it would make sense to warn about it, since the odds of that being
legitimate are nearly zero, and the same goes for any other unary
operator.
I think that is Andrei's original suggestion:
the sequence "=", "+", whitespace should be rejected.
He says nothing about "=","+" without the whitespace.
