This patch might regress the performance of the Currency class and by extension the Amount class. Since Amount is on a lot of hot paths in the client we should make sure this isn't a major problem. As for compatibility, this patch is a major change, but it should maintain the public interface very well, which the exception of some strange edge cases (e.g. Currency.from_json(1337)), which weren't well-defined before anyway. Any code that accesses _value directly (shame on you!) will need to be fixed. There aren't any such references in ripple-client or the rippled test suite, so I think we're looking pretty good.
