/**
|
||
|
|
IntIterator is used for implementing interval iterations.
|
||
|
|
|
||
|
|
It is usually not used explicitly, but through its special syntax:
|
||
|
|
`min...max`
|
||
|
|
|
||
|
|
While it is possible to assign an instance of IntIterator to a variable or
|
||
|
|
field, it is worth noting that IntIterator does not reset after being used
|
||
|
|
in a for-loop. Subsequent uses of the same instance will then have no
|
||
|
|
effect.
