I propose to add support for start ..+ length
expression, which is equivalent to start ..< start + length
(e.g. 100..+5
is the same as 100..<105
).
This is especially useful for slicing when start
expression is quite long.
Also, I do not think start ..+ length
needs a special separate range type, i.e. it can be just of type OpenEndRange
with endExclusive
set to start + length
.
