It extends to Gaussian integers (complex numbers whose real and imaginary
parts are both integers), but there is no support for those in Scheme
except as a subset of the general complex numbers.

Writing a SRFI for Gaussian integers would be a Good Thing.

Clear?  Huh!  Why a four-year-old child could understand this report.
