This was recently suggested to me as an extension:

~~~ruby


class Object

# An identity method that provides access to an object's 'self'.

#

# Example:

# [1,2,3,4,5,1,2,2,3].group_by(&:identity)

# #=> {1=>[1, 1], 2=>[2, 2, 2], 3=>[3, 3], 4=>[4], 5=>[5]}

#

def identity
self

self end
end
end
~~~


First, is such a method commonly useful enough to warrant existence?

Second, it makes me wonder if #self should be a public method in general.
