[Numpy-discussion] numpy requires tuples for indexing where Numeric allowed them?

I'm fighting conversion from Numeric to numpy. One change that doesn't seem documented is that I used to be able to select items using lists and now it seems that I have to convert them to tuples. Is that correct and is there a function buried in there that will accept a list for indices? Any reason that item() can't take a list? The weird thing is that it doesn't blow up right away when a list is passed in an array ref but rather returns something I don't expect. I work with lists rather than the implicit tuples of a function call because then I can work with arbitrary dimensions. In the meantime, I guess I can just convert the list to an otherwise unnecessary tuple. Jim
