Hi,
A little more than a year ago I have made a proposal to extend LibGee
when I rewrote the tests for it, but at that time there was not much
interest in the changes. It may be good to repeat what I had in mind
at that time:

> Map interface

Some of the things have already been proposed and there are other
things on my mind that could be done.
I still have the code of the changes (including tests) somewhere - I
will seek them out and merge them with the latest libgee version.
Maybe it would be a good thing to add on the libgee wiki a subpage
with proposed changes/additions so that all this things aren't
forgotten.
Regards, Tomaž
