Mailman 3 Fwd: Re: PEP 472 - slices in keyword indices, d[x=1:3] - Python-ideas

      I attempted to send this yesterday, but used the wrong sender email 
address and it got rejected.

I think this is still relevent, just to confirm I understand the 
proposal correctly.

I think it is worth directly discussing the availability of slices in PEP
472-style keyword indices, since we seem to have mostly converged on a
dunder method signature.  This is an issue that has been alluded to
regarding keyword-based (labelled) indices but not directly addressed.  The
basic syntax would be something like d[x=1:3].
I read that as equivalent to `d[x=slice(1, 3)]`. Is that your intention?

If that is your intention, then a big +1.

If your intention was `d[slice(x=1, 3)]` then I think you would have to 
justify what it means and why you want it.
