Can't count array elements

[BatmanAoD]

I'm not sure if this is a bug or something that's just not implemented yet:

osh$ arr=(foo)
osh$ echo ${#arr[@]}
Traceback (most recent call last):

In any case, is there a working way to count arrays in osh yet?

It does not work with [*] either.

I confirmed that this is a bug. Thanks for the report!

I thought there was a spec test for the length of arrays but apparently not.
