Your idea look good to me. I think about it but afraid inconsistent of output
(print 3 filed for character and 2 for fixnum). That is why I don't suggest
this solution...

One essential point is that if some test check fail all followed tests doesn't
executed due to this bug. So this must be fixed in any way...
