Reviving this old thread since this is hitting me again today.  Is there any momentum on extending tuple unpacking to within slices?

I didn't think of this when we were discussing 448.  I ran into this today, so I agree with you that it would be nice to have this.

Best,

Hi,

I've been thinking about the * unpacking operator while writing some numpy code. PEP 448 allows the following:

   values = 1, *some_tuple, 2
   object[(1, *some_tuple, 2)]

It seems reasonable to me that it should be extended to allow

   item = object[1, *some_tuple, 2]
   item = object[1, *some_tuple, :]

Was this overlooked in the original proposal, or deliberately rejected?
