None of Racket, Gauche, MIT, Gambit, Chicken with the numbers egg,
Bigloo, Guile, Kawa, Scheme48, SISC, Chibi, Chez, SCM, Ikarus,
Larceny, Ypsilon, Mosh, STklos, SSCM, and Scheme 9 distinguish between
rectangular and polar complex numbers.

[R]eversing the apostolic precept to be all things to all men, I usually [before
Darwin] defended the tenability of the received doctrines, when I had to do
with the [evolution]ists; and stood up for the possibility of [evolution] among
the orthodox --thereby, no doubt, increasing an already current, but quite
undeserved, reputation for needless combativeness.  --T. H. Huxley
