what overhead? It's all in your imagination :)
a..b is confusing and bad UI. a..b means for humans the range of a till b and not the tuple of the two. 
if I see something like "hello"..42 I would assume the person who wrote this was high on something.

multi dimentinal slicing should accept an integer range type and NOT a tuple.
