class Object
# Returns +value+ after yielding +value+ to the block. This simplifies the
# process of constructing an object, performing work on the object, and then
# returning the object from a method. It is a Ruby-ized realization of the K
# combinator, courtesy of Mikael Brockman.
#
# ==== Examples
#
# # Without returning
# def foo
# values = []
# values << "bar"
# values << "baz"
# return values
# end
#
# foo # => ['bar', 'baz']
#
# # returning with a local variable
# def foo
# returning values = [] do
# values << 'bar'
# values << 'baz'
# end
# end
#
# foo # => ['bar', 'baz']
#
# # returning with a block argument
# def foo
# returning [] do |values|
# values << 'bar'
# values << 'baz'
# end
# end
#
# foo # => ['bar', 'baz']
def returning(value)
yield(value)
