Hi All,

<= /div>
My proposal is very simple. Just remove completely=C2=A0forward r= eferences because of confusion that it makes until it is not too late !!

Sorry, you're about six years= too late.
=C2=A0
Basically if we have the following example:

=C2=A0 =C2=A0 template<typename T>
=C2=A0 =C2=A0 v= oid setItem(T && t)
=C2=A0 =C2=A0 {
=C2=A0 =C2= =A0 =C2=A0 =C2=A0 ...
=C2=A0 =C2=A0 =C2=A0 =C2=A0 // T can be = lvalue or rvalue reference as all of you know =C2=A0 =C2=A0 =C2= =A0 =C2=A0
=C2=A0 =C2=A0 }

But it confus= es ( I think ) all of us.
Actually it even violates SOLID = principale (S - Single responsibility). I should use one function only for = rvalue references or for lvalue references. Mixing together h= andling of both references is bad practice.

What d= o you think ?
