[Python-Dev] Fix _PyEval_SliceIndex (Take two)

(More readable second paragraph)

Hello again,

There is a great discussion going on the numpy list regarding a proposed 
PEP for multidimensional arrays that is in the works.

During this discussion a problem has resurfaced regarding slicing with 
objects that are not IntegerType objects but that have a 
tp_as_number->nb_int method. Would it be possible to change

_PyEval_SliceIndex  in ceval.c

so that rather than raising an exception if the indexing object is not 
an integer, the code first checks to see if the object has a 
tp_as_number->nb_int method and trys it before raising an exception.

If this is acceptable, it is an easy patch.

Thanks,

-Travis Oliphant
