1. This can get arbitrarily expensive if there are parameters involved (temps have to be constructed, copied, & destroyed) and those costs will be hidden.
2. At some point, heroic efforts to coerce one type to another will subvert the point of a type system. After all, if the designer of bar() intended the return value to be the point, wouldn't such a conversion hide a bug?
