As mentioned over IRC.

Why do this with Throwable (which raises the WTF factor), why not just
add a generic default case:

try {
	throw new Bar;
} catch ($e) {
	// do stuff with the exception
}

sure introspection will suffer, but I'm against anything that forces a
developer into a contract they may not want to make.
