[PYTHON MATRIX-SIG] Slice expressions

[Konrad Hinsen]

What happened to the slice generator that was in Numeric in earlier
versions? It seems to have disappeared, with no visible replacement.

Just in case someone else needs it, here's the definition that I just
put into my copy of Core.py:

----------------------------------------------------------------------
class _index_expression_class:

    def __getitem__(self, item):
        if type(item) != type(()):
            return (item,)
        else:
            return item

index_expression = _index_expression_class()
----------------------------------------------------------------------
