Line 2:
'''Wren-trait''' is a module which provides the abstract classes: Comparable, Cloneable and CloneableSeq. The first of these enables child classes to easily support the basic comparison operators and the latter two enables such classes to identify themselves as ''cloneable'' given a suitable mechanism.
 
It also contains the wrapper classes: Stepped, Reversed and ReversedByRef. The first two of whichthese enable sequences to be iterated in either (or both) a stepped fashion (steps > 1) or in reverse. The third enables a value to be passed ''by reference'' to a method or function.
 
It is the fifth in a series of modules (listed on the language's [[https://rosettacode.org/wiki/Category:Wren main page]]) designed to assist with writing Rosetta Code tasks so the same code does not have to be written or copy/pasted time and time again thereby bloating a task's script code unnecessarily. It is also small enough to be used by other modules in the series which are usually organized and written to avoid inter-dependencies.
