[Chicken-users] Nested hash-tables, and so on..

[mfv]

Hi, 

I've been fooling around a bit with chicken, and now I am on towards a small
project. I have a question regarding the performance of list and
hash-tables.

I plan to use nested hash tables as a data structure e.g.

hash-table1
          |
          key1
             |
             hash-table2
                       |
                       key2
                          |
                          list/string/some data

Are there objections to such a nested hash table structure e.g. should one
keep it as flat as possible and use multiple hash-table is parallel  in order 
to maximize performance?
