__get__(index, ...) # I want an ITEM. __getslice__(slice-object, ...) # I want a SLICE.
I like this (although it would be safer if the new-style __getslice__ had a new name as well).
This would require detection of whether any of the components of a multidimensional (i.e. tuple) index were slices
Doesn't the parser know this already?
Yes.
By the way, if you're going to make a clear separation between items and slices, then either *none* or *all* of the members of a multidimensional index should be slices, and mixing them should be an error!
Huh? The way I understand this, mixing indices and slices is used all the time to reduce the dimensionality of an array. E.g. if A is a 2-dimensional array, A[0] is a 1-dim vector, and so are A[0, 1:-1] and A[:-1, 1]. --Guido van Rossum (home page: http://www.pythonlabs.com/~guido/)
