Yeah, sorry about that, I really should update this wiki page. I gonna try
later this afternoon/evening.
Glad it works, though.
However, that only part of your problem:
With concatenate, what unit should take precedence ? In your example,
concatenating unit_ary_1 and unit_ary_2 should give a unit_array w/ meters as
units. But what if you concatenate unit_1 and unit_3 ? Meters or feet ?
The idea would be to write a custom concatenate function, that would convert
the units of each argument to the unit of the first one (for example), and
call numpy.concatenate. Or something like that.
