Well, converting between types is pretty much what Unchecked_Conversion is in
the language for. It may look a bit ugly and scary, but that's because the
activity you are doing is *also* a bit ugly and scary (if sometimes nessecary).
Consider it truth in advertising. :-)

Note that since Unchecked_Conversion is a function, an assignment of the value
will occur. That's why we usually perform it on pointers when the target data is
large buffers.
