Ah, T time! ;-)

I meant that the static method didn't belong in GThing at all. The
author of the call site factors it out of his code, and keeps it near
the call site, in order to deal with an issue that arises very
specifically out of the design of that site. Ideally, it would be an
Ada-like local method, but he has to settle for a near-by static. The
author of GThing is unaware of it, and is not responsible for it.
