C++11 constexpr would handle the function case while also working for
user defined types. This suggests that the template version is less
generic.

Hi,

Sometimes the bound values are know at compile time. Could we ensure
that the compiler could optimize the following code

   auto res = clamp(val, 1, 100);

If this is not the case, I was wondering if it is worth adding a static
clamp function that has its bounds defined as template parameters.

   auto res = static_clamp<1,100>(val);

Best,
Vicente
