std::set has the same number of non-optional template parameters as std::vector,
so it's actually no problem at all.  That is, if you're happy with the defaults
for the optional template parameters.

Not always, as said above.

So what? Any reasonable lambda library doesn't work with MSVC, either, but
that's no reason not to have it.

I'm just suggesting an alternative. If it's not an improvement, ignore
