1. Minor question: I coulda swore the first time I fixed this I dug
around and discovered :ensure-float and used that in my DEFCFUN.
The second time I ran into it I went looking for :ensure-float and
could not find it. Found :ensure-XXX for a couple other things in
the UFFI-compat bit. Maybe it was one of the XXXs. No big.
Hmm, I don't remember.
2. Am I missing something? Is there some reason we cannot have an
ensure-float? Is it one of those deals where for some obscure
reason unbeknownst to me there is no reliable way to guess what is
needed and programmers need to Just Provide the Right Type?
We define ensure-float and ensure-double in cl-opengl, seems to work
pretty well. I think a :coerce type would be interesting:
(:coerce <type>)
I haven't thought about which (primitive) types this would make sense
for or how hard this type should try to convert things.
