I guess the parser would have to change for the above to work.
Right now you'd have to say for i in 0:...:10
and I'm not sure if that's syntactically valid.

As far as I can tell, the only current use of ellipsis is in
dictionary indexing.  One can imagine mapping a database into a
dictionary, so db[4:...:19] does a select on those elements.
