Yeah, I think hiding the type-casting is worth it alone. I was just
confused by your remark.

Yeah, I'd agree that is a much better name. Since there's an "incr",
having a specific "set" makes it clear that we're overwriting.

OK. Then I guess we can't cheat our way out of picking a name with
strmap_getint(). :)
