What is the benefit of 'auto ref' over 'in' as you are changing
a nor b?
Because
less_than (T)(T a, T b)
(or in, or const T) will copy a and b on their way into the
function. Usually this is ok but certain data structures I use
are not intended to be copied, or they are just very large or
have very elaborate constructors that take up time and resources,
or something.
I don't know if inlining would solve this or not but as far as I
know there is no way to rely on inlining currently.
