Actually, since you don't know if the cast is really valid, it failing is a regular outcome.

As such, an exception (which is reserved, appropriately, for *exceptional* events), is totally the wrong approach to use.

Note that with the current behavior, you can incur the runtime speed loss of throwing an exception if you _want_ to, by using the above templated wrapper, but if throwing an exception were the only possibility, you couldn't possibly get that speed back.

So it really is better this way. :)
