Missing line:

Bye,
bearophile

Wouldn't it be better to do this at the call site anyway? Just 
use a simple function.

Unqual!T unconst(T)(T val)
if (isScalarType!T)
{
    return val;
}

void foo(T)(T a, T b)
{
    a = b;
    b = a;
}

void main()
{
    const int x, y;
    foo(x.unconst, y.unconst);
}
