My last comment on this ...

As a user, I would want to know *now* that the behavior of 
scalar indexing is targeted for a change, especially since 
I can easily write my code *now* to avoid being affected by 
this.

E.g., suppose instead of incorporating Travis's patch (which 
I support) NumPy adopted Gael's proposal (and Tim's?) to raise 
an IndexError for scalar indexes.  In either case, code 
written with non-scalar indexes will continue to work as 
expected, but code written with scalar indexes will often 
break.

So it only seems fair to include a warning now.
