>>> a = set( range(5) )
>>> a[0]

Traceback (most recent call last):
  File "<pyshell#15>", line 1, in <module>
    a[0]
TypeError: 'set' object is unindexable

No point it needing to be indexable either.

It's also worth noting that removing an object from a container
(.remove) is different than proposing the object goes to GC (del...)

Have to disagree that del[] on a set makes any sense.

Tired, and it's late, so probably typing rubbish, but felt okay when I
started reading the group :)
