I know Mike was being silly with `notanidiot's spelling, I was going
to suggest the same thing, spelt `-Wexpert'. The implication of
-Wnotanidiot is that anyone who doesn't turn it on is an idiot,
we'll alienate our user base, and they'll turn the flag on anyway
-- then get confused when on conversion sequence is selected over another.

Also, the meaning should be something like
	"Do not warn about confusing and commonly misunderstood
	parts of the standard"
[perhaps the sense should be inverted, and the flag on by default]

That way we can augment other parts of the compiler too. It shouldn't
go into -Wall, as those warning (which I happen to like), can be turned
off by suitable reworking of the source code.
