I wanted a symbol that evoked "this value comes from the left hand side of the assignment". Most symbols containing a `=` either already mean some sort of assignment, or look like they might become an assignment operator in the future. I went with an arrow, pointing to the target, but one that doesn't conflict with any existing arrow symbols. When this idea first surfaced on ideas it was spelled `@@` which doesn't really seem to evoke anything; maybe that's good as it can't be confused, but I was hoping for an intuitive symbol. `$` also made some sense to me as referring to the target, but felt maybe out of place in python. So perhaps `$`, `%%`, or `@@`? It doesn't feel important enough, even to me, to use a keyword, and soft keywords are out because of where it is allowed. I'm open to other suggestions.
