If you mean that they should be overloaded by the library itself, then this is
not necessarily a good idea. It is not possible to guess what should be the best
return type of arithmetic operators in general case. For some applications
returning a constrained value would be OK (but again there is the problem that
the constraint may reject the modified value) while for others it's better to
return the underlying type.
