|
||
A Forward Sequence is a Sequence whose elements are arranged in a definite
|
||
order. The ordering is guaranteed not to change from iteration to iteration.
|
||
The requirement of a definite ordering allows the definition of element-by-element
|
||
equality (if the container's element type is Equality Comparable) and of
|
||
lexicographical ordering (if the container's element type is LessThan Comparable).
