Okay, the details are at ComplexRepresentations now. Racket, Kawa, Chez,

Vicare, Larceny, Ypsilon, !IronScheme, Spark support (imag-part 2.0) => 0

even though they don't support mixed-exactness complex numbers.

There are two reasonable semantics for (image-part x) for rational x.

One is exact 0, the other is to copy the exactness from x. There

was a bug in Chibi - it now always returns exact 0.
