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?
