Not necessarily. You really can't tell whether the value is copied
only from the expression at the call site.

For instance, if the declaration was
void Test_Method( Test_Struct% info);
there wouldn't be a copy involved.

Nonetheless, I agree implicit boxing is dangerous and it
shouldn't be in the language IMHO. But I'm afraid you need
to convince someone else.

FWIW, I use a helper function box or box_cast to do an
explicit cast.
