The benefit of the latter is that you know the number of "slots" ahead of time so you can populate 
the data without needing to allocate memory.

In that case I don't think the benefit I mentioned wrt data structures matters because 
the I/O speed will be your limiting factor.

My suggestion would be to start with the more expressive vanilla object-- [text]-- and see 
if it fulfills your needs. Keep in mind though that it is at core not a key/value store but instead 
a 2-dimensional array of atoms. E.g., you can decide that the first item in each line is your 
key, but the text class interface does nothing to prevent you from adding more lines that 
duplicate that same key.

Hello all,
I'm looking for something analogous to the Max "coll" object, or a python dictionary, or anything with key value pairs.  
I'm aware of the 'cyclone' and its 'coll' object.
i'm wondering if there is a pd-vanilla friendly alternative to this 3rd party external.
any hints?
thanks in advance,
