Since this is expected, could the test use a static_cast to the right type?

v6 = static_cast< t_var6 >(58);

Does this quiet the warning?

Or must it be v6 = static_cast< unsigned short >(58); ?

Either way this would document that casting/converting takes place?

And perhaps users should do this too? The static_cast documents that the author
has thought about this.
