unittest {
Mass m;
Velocity v;
pragma(msg, typeof(m * v).stringof);
pragma(msg, typeof(v * m).stringof);
static assert(is(typeof(m * v) == double));
static assert(is(typeof(v * m) == double));
}
Currently the type of m * v is Velocity, and the type of v * m is Mass. The
only reasonable type of an operation (if it compiles at all) should be double,
obtained after both operands are converted to their supertype.
