Re: [Scheme-reports] Numerical example (real? -2.5+0.0i)

That's reasonable: in fact, SCM doesn't support exact/exact complex
numbers either, which is perfectly fine.  It just means that no general
complex number can be real.

The rationale here is that a number with imaginary part 0.0 isn't
necessarily on the real line, since 0.0 just means a number x such that 
0 < x < the smallest representable inexact number.
