Ellipsis outside a slice

[Chris Perkins]

Is there a reason why the ... notation as a literal for Ellipsis is
only allowed inside a slice? Would allowing it elsewhere frighten the
parser?

It would complicate the parser for no purpose. One can already access
the singleton ellipsis object by it name -- Ellipsis. It was invented
and added for use in extended slices by Numerical Python and has no
grammatical use outside slices.
