And the other, with apologies to WS Gilbert, isn't. But it really
doesn't matter. As long as that number is greater than zero, changing
this will be a problem.

I've not seen a single suggestion that doesn't have downsides as
annoying as implicit concat's. In the absence of a *strong*
alternative, I would be against any sort of change; why break code if
the replacement is hardly better than the current?
