04:42 PM Ruby Bug #15857: <=> の右辺が <=> を実装していない場合の振る舞い

In doing a bit of maintenance work for the ruby-units gem this issue came up. I think there may be some additional methods that now need to be generated in the C code. See the following example.
```
c = Complex(1,0)
c <=> 1 # => 0

=begin
I'm fine with adding a comment, however the one you added does not really clarify the matter (at least not to me).

12:25 PM Ruby Bug #3563 (Closed): problems with exponentiation, cbrt

=begin
# nothing required

> (-27)**(Rational(1,3)) #=> (1.5000000000000004+2.598076211353316i)

I would expect that this would return -3

> Complex(1.5000000000000004,2.598076211353316)**3 #=> (-27.000000000000007+1.2434497... kolbrich (Kevin Olbrich)
