Ah! Good catch.

I've added:

Note that ''+0"" is a real number and thus covered by the first clause.

In order to avoid future confusion.

In the example about equality and identity, wouldn't it be helpful to  
extend the example to include, say, a universal restriction on  
a:numberOfChildren to be min/maxInclusive +0. This would show that -0  
and +0 were equal?

Cheers,
Bijan.
