You mean start..(end-1) -- but apart from that, because start...end is 
faster than start..(end-1) unless the compiler recognizes start..(end-1) 
as a special case and translates it to start...end.

And since programmers typically don't know whether the compiler does 
that special case or not, many programmers will take the time to 
"optimize" with endminus1=end-1 and then use start..endminus1.

All of which can be eliminated simply by having the exclusive range in 
the first place.
