It's the same reason why one cannot pass, say []byte as an []int. The
backing arrays of the two slices have incompatible memory layouts. To
make it work the compiler would have to inject code like
(schematically)
var tmp []int
for i, v := range byteSlice {
tmp = append(tmp, v)
}
callTheFuntion(tmp)
It is doable but it has a cost which the language designers preferred
not to hide.
