The runtime was handling the message lookup correctly in this case, but only as a side-effect of the fallback code from when type-dependent dispatch is not possible. This resulted in a confusing warning message, telling you that you were calling a method with an incorrect signature, when the two signatures that it printed were the same. This case is now handled correctly, so the warning disappears (unless you really are calling a method with the wrong signature and have TDD enabled).
