In my book, every cast is wrong, and widening casts are doubly wrong
because they're implicit. Casts are marginally acceptable if they're
needed to adapt to a poorly designed and/or hardware/platform-specific
API. But in this case, all the values involved appear to be parameters
or return values of our own private functions.
