Hmmm. There's no way to do this without telling Foo its name explicitly.
If there are two names for a Foo instance, what would you like 'whoami' to
print?

>>> foobar = Foo()
>>> another_name_for_that_foo = foobar
>>> foobar
<__main__.Foo instance at 807e0b8>
>>> another_name_for_that_foo 
<__main__.Foo instance at 807e0b8>
>>> 


See the problem?
