The simple answer is No, and all the answers agree on that point.
It does beg the question of what an identity function is, though.
My contention is that an identity function is a do-nothing function
that simply returns what it was given:
--> identity(1)
1
--> identity('spam')
'spam'
--> identity('spam', 'eggs', 7)
('spam', 'eggs', 7)
I don't see why this last case should hold. Why does the function take
more than one argument? And if it does, then why doesn't it work like this?
--> identity('spam')
('spam',)
(because then it wouldn't be an identity function!) Trying to handle
the multi-argument case seems like it adds an unneeded special case to
the function.
