It's not implicit in this case, it's explicit. + is the function you're calling. And there's power in having mathematical operations be functions that you can manipulate and compose like all other functions, instead of some special case of infix implicit (to me, yeah) function calling, like 1 + 2, where it's no longer similar to other functions.
