[Numpy-discussion] ragged array implimentation

Hi folks,

I'm setting out to write some code to access and work with ragged arrays 
stored in netcdf files. It dawned on me that ragged arrays are not all 
that uncommon, so I'm wondering if any of you have any code you've 
developed that I could learn-from borrow from, etc.

note that when I say a "ragged array", I mean a set of data where the 
each row could be a different arbitrary length:

1, 2, 3, 4
5, 6
7, 8, 9, 10, 11, 12
13, 14, 15

In my case, these will only be 2-d, though I suppose one could have a 
n-d version where the last dimension was ragged (or any dimension, I 
suppose, though I'm having trouble wrapping my brain around what that 
would look like...

I'm not getting more specific about what I think the API should look 
like -- that is part of what I'm looking for suggestions, previous 
implementations, etc for.

Is there any "standard" way to work with such data?
