Question mark added on trunk.

They are considered real but not rational, as in R6RS, and I have added
text to that effect to 6.2.5.

In addition, complex numbers are finite iff their real and imaginary
parts are finite, and NaN if the real *or* imaginary part is NaN.  This
is an extension to R6RS.
