I (slightly) disagree.  In a past life of building error-checking
tools, we found that it was sometimes useful to be able to warn about
things like this when a class was designed, rather than it was used.
It's not a *big* deal, but think Karsten's suggestion is better; we
need, eventually, to find a way to control individual warnings.  Then,
all we have to argue for is sensible defaults... :-(

In the short term, disabling this warning might be the way to go.
Perhaps it should be `if (0)'.  This will make sure that the code
continues to compile (as opposed to `#if 0', which is more likely to
lead to bit-rot...).
