### Methods

enum_for to_enum

### Public Instance methods

obj.to_enum(method = :each, *args)
obj.enum_for(method = :each, *args)

Returns Enumerable::Enumerator.new(self, method, *args).

e.g.:

       str = "xyz"

       enum = str.enum_for(:each_byte)
       a = enum.map {|b| '%02x' % b } #=> ["78", "79", "7a"]

       # protects an array from being modified
       a = [1, 2, 3]
       some_method(a.to_enum)
