Hmm, interesting point, I agree with you. It's particularly telling
that I got sucked into designing that sort of API, even though I know
it's got this problem. I guess that counts as an argument against the
late bound defaults proposal - or maybe even two:

1. It's hard (if not impossible) to wrap functions that use late-bound defaults.
2. The feature encourages people to write such unwrappable functions
when an alternative formulation that is wrappable is just as good.

(That may actually only be one point - obviously a feature encourages
people to use it, and any feature can be over-used. But the point
about wrappability stands).
