Not much, really. I'm still intending to do these things,
I just haven't got around to it yet. I've been too
busy with other things to find the time to concentrate
on Pyrex much recently.

Yes, another thing I'm considering is teaching it about
some of the builtin types such as list and dict, so you
could write

   cdef list mylist
   mylist.append(foo)

and have it generate PyList_Append(mylist, foo).
