When you're drawing this sort of diagram then what references are held
by an object are more important than what interfaces it implements.

Personally I think it's a bit silly to insist on a diagram model where a
box with an arrow in it pointing at an int object can't be represented
by a box with an integer in it (where 'int' is any immutable type -
string, tuple, even range), but people don't like boxes with integers in
them for some reason.
