I've been doing this for a long time and today this would be taken as
two operators. The assignment and unary +. Since A = B is the same as A
= +B, it would perform the same as a simple assignment. The only reason
I can see to do this legitimately is for clarity reasons, i.e., if what
follows the "+" is almost always used as a negative but this use is an
exception. But more likely, at some point there was something between
the = and + at one point that got deleted, but the "+" was left. Since
this is "the default", there would be no coding or operational errors
from leaving it in.
Then again, it could have been intended to be += and you've found a
heretofore undiscovered bug! All you have to do is press Shift at the
wrong time (not that I've ever done that).
