When writing some template <typename T> class
that should work for built-in and user defined types,
I have to use free functions f(T t);
I cannot write t.f().

This makes name resolution more difficult for the
compiler and forces me to use traits.

If the compiler tries to change t.f([other args]) to
f(t,[other args]) when it cannot find a proper matching t.f(),
much less free functions will be needed.

Wouldn't also be the std::swap problem

be solved ,
when i.swap(j) were defined as swap(i,j)
for built-in types?
