[Scheme-reports] grammar of numbers

[Michael Montague <mikemon@x>]

The grammar of numbers on p. 62 appears to require that complex numbers 
without a real part must have a sign on the imaginary part.

For example, 100i must be written as +100i. Chibi happily accepts 100i 
and treats it as 0+100i.

Is there an error in the grammar or is Chibi providing an extension?

Thanks.
Michael.
