I don't think we ever decided on the `()`, but it's started to become a standard. I don't care too much, though I do think that in at least many cases, having the `()` makes it more obvious it's a method. However, as @xabbuh knows well, I at least sub-consciously must not *always* love it, because I leave it off almost every time when writing :).

I'm not really sure if we should make it a standard or not. I would lightly prefer *against* making it a standard, and instead use it only when we think it's useful.
