<blink>?  What happened to minimalism...?  Couldn't this be just as
well have been coded...:

	typedef T::i dummynameoftype; // no syntax ambiguity here
	...
	dummynameoftype *var; // no ambiguity here either

Was a whole new keyword really introduced just for the purpose of
avoiding the template author the chore of thinking up a dummy type
name in this situation...?  Or am I missing something here...?
