<div dir="ltr">I'm not completely sold on the proposed change but, if we were to do something like this, I suggest we include `fixity` as a parameter and come up with something for `assignment` (`true` in my example is admittedly suboptimal ).

(To be fair, I wasn't comfortable with the old way, either.)<br><br>Here's what I suggest. Usually, a bunch of parameters modifying a declaration would go in a parenthesized list after the particular keyword they modified, and in this case, `associativity` and `precedence` (and probably `assignment` too, though I don't know for sure since it's not documented) are only valid on an infix operator.
