 Good to know - some of this code seems a little crusty (and I've found a
couple of bugs just trying to verify that it still works correctly).

Not sure about the wording in your second sentence.  At the time we

I meant a code branch e.g. "if", or a preprocessor "#ifdef" in this case.

I think I've gotten confused by some of the indirection in the class
definitions - the top level only adds the numpy constructor, and then
everything else is put in several levels down - and in some of my tests it
looked like the numpy routine was mistakenly doing all of the construction
(which ended in much the same results).
