Comment #5 on issue 2149 by address@hidden: Patch: Creates  
non-negative-integer? predicate.

That's what I meant with "Scheme has a definition".  non-negative-integer?  
however is not really appropriate since negative integers don't even make  
sense in the context where you would want to use that predicate.

So something like unsigned? (somewhat ambiguous since the term does not  
really rule out a subset of fractions or floats) or unsigned-integer?  
(again awkward, but less so than non-negative-integer?) or just count? seem  
better suited.
