[PD] Associative list

[Phil Stone]

Hi Chris,

This sounds like a great thing for vanilla Pd.  I've had need of 
something just like this more than once.

Having worked a bit with [pool] recently, especially as it is used in 
Memento, I'd venture that you'd have to go quite a bit further to match 
its functionality, though.  It's like a miniature in-memory file system, 
with directories, clipboard editing, and more.  It would be laudable to 
do a "pure" Memento, but I think much of the hierarchic potential of 
[pool] for state-saving has barely been scratched, and in that direction 
lie some very interesting capabilities.
