description

    
The list of standard features needs more careful review.

In particular, exact-complex seems odd - it's more likely
that we want to test for any complex, and if we really want
to distinguish exactness why not inexact-complex?

Okay, back home.  Support for all types of complex numbers:  MIT, Gambit, Mosh, STklos.  (Also CLISP.)

Support for exact/exact and inexact/inexact complex numbers only (no mixed exactness): Racket, Chicken (with the numbers egg), Scheme48/scsh, Kawa, Chez, Vicare, Larceny, Ypsilon, !IronScheme.  (Also Armed Bear CL, CMU CL, Clozure CL, ECL, GNU CL, Steel Bank CL.)

Support for inexact/inexact complex numbers only: Gauche, Guile, SISC, Chibi, SCM, KSi, Scheme 7, UMB.  

No support for complex numbers at all:  Bigloo, Ikarus, !SigScheme, RScheme, Elk, VX, Oaklisp, Owl Lisp.

I don't know of any Schemes that support exact complex numbers but not inexact.  The normal cases are all types of complex numbers, or inexact-inexact complex numbers only (like SCM and some others -- I don't have access to my suite of Schemes today).  So the `exact-complex` test is for the ability to do exact arithmetic on complex numbers.  To test for the presence of complex numbers of any kind, test for `(module (scheme complex))`.
