I think this fix is "OK" as a stopgap, but I think what really should happen is position be put through unit conversion (which I don't think it is). But I'll leave that for someone who actually uses boxplot to make sure it is done properly... Still think this should go in to make array-like things w/o units work OK. Happy to be told that someone's favourite units used to work, but break w/ this change.

This is a good fix for the case described in the ticket, but I think the code will continue raising obscure error when positions are not numbers. Can you add a check after this line about the dtype of the array being a number? Maybe something like:

if not isinstance(positions.dtype, numbers.Number):
     raise TypeError("positions should be a iterable of dtype number, but found dtype %s" % blah blah blah.)

When we end up supporting something else than numbers, this can be updated.

I couldn't quite get that check to work; I had to check the first element. But if there is a better way, let me know.
