One question - is sv even supposed to be public? It is a "static const bool"
(so this is what I'd call a definition, not a preinstantiation, but that's a
nit). I'm guessing sv is not really supposed to be exported, or we would
have given it a more meaningful name. Rather, it looks like it is just a
shortcut to simplify the rest of the code. We do this all the time with
typedefs, which I've always assumed had no great cost in compile time. It is
rare to do it with const parameters like this, but it is done to improve
readability. I guess I had always figured that the compiler would optimize
the definition away (would it if it were private?). Anyway, if it isn't
supposed to be public, we could make it go away altogether.
