I do this pattern often:

if (0 < x && x <= ; 100)

And would love a simple `std::between()` th= at would take two arguments and an optional third (compare function) argume= nt.


templated<typename T= , typename Compare>
bool std::between(T lower, T upper, Compar= e comp)
{
=C2=A0 =C2=A0 return comp(lower) && c= omp(upper);
}

Does anything like this ex= ist? Should I propose it!?
