Enumerator

A class which allows both internal and external iteration.

An Enumerator can be created by the following methods.

• Kernel#to_enum

• Kernel#enum_for

• ::new

Most methods have two forms: a block form where the contents are evaluated for each item in the enumeration, and a non-block form which returns a new Enumerator wrapping the iteration.
