It would look consistent, but it would behave very differently. x..y for 
foreach and slices is exclusive of the y, while case x..y is inclusive.

Creating such an inconsistency would sentence programmers to forever 
thinking "which way is it this time".

To avoid such confusion an obviously different syntax is required.
