-1.  The speed of randrange() is crucial for many applications;
indeed, that's the only reason it abused default arguments to begin
with (i.e., to make `int` et alia fast local lookups).  Digging
through a dict to guess which API was invoked would ruin that.

And the ZODB tests in question deserve whatever they get ;-)
