Also what was your intention? func() practically takes a short
parameter. Maybe it's signature should be
void func(short x) {...}
If that's a problem on the calling site, maybe that can be
fixed?
I believe the intention was to show an issue with the language, not to
make a
function that assigns to a short and a byte only to throw them away.
Perhaps he needed to do some intermediate calculations at higher precision,
perhaps he needs it to be an int for interfacing with a C function, etc.
