Funny, I thought the "repr invariant" was exactly the opposite thing, that _eval_ (or literal_eval) of repr should give back the starting object. And that's what I intended to preserve here. It's obviously broken now.

Ok, alternate suggestion: can at least ast.literal_eval be fixed to work in the same way as complex constructor? Because it's not much of a "literal" otherwise...
