Well, I was kinda winging it and didn't actually use the interpreter
for some of those. The point is that the output I gave _could_
reasonably be that of the interpreter (if the implementation details
of repr() were slightly different; it would still meet the spec
anyway) and illustrates the eval()-repr() relationship.

Just keep in mind the equivalence rule and what repr() does should
become obvious.

Cheers,
Chris
