I answered off list (because besically I'm an idiot). So if you like, 
read up the current news. :)

Hi Wildemar,

Thanks for the answer. I did make something myself after i could not
find anything, just because it was fun to do :-) I did saw array but
it was not for object, only for small types like int, char, etc to be
used for quick but efficient buffers of raw data (at least it looks
like that).

The list I created uses a strong type check to make sure all objects
in the list are of the same type, like

ol = objlist.ObjList(class_name = SomeClass)

Now only classes that are an instance of SomeClass are allowed in the
array, ObjList mimics a normal list, it can index, iterate, find,
delete, append items so it was basically a drop-in replacement for my
_list = [] solution

If you are interested i can send you the source. I created a py.test
module as well to test every method intensively.

Regards,
- Jorgen
