SyntaxError: invalid syntax

I don't see how that's an argument, we are talking about a syntax extension.   Slice builder syntax is only every allowed in a subscript.  Edit my original grammar change proposal to:

```
subscriptlist: ... | kwargsubscript (','  kwargsubscript )* [',']
kwargsubscript: NAME '=' subscript
```    

Now slices are allowed in keyword arguments.

I wasn't making an argument, I was wondering what exactly we are even discussing. It seems like people are inventing new syntax willy nilly in this thread and I am getting very confused :)
