Looks very good. A couple of points:

- I’m not convinced about ‘absoluteValue’, with an associated type. I think it 
should return the same value as ‘abs()’ or have a different name if it’s really 
needed at all; the example of a print function is a bit weak IMO.
- I’m not sure about an ‘nthWord()’ getter without a corresponding setter.
- I would like ‘floor’ and ‘ceil’ to be part of the standard library (or some 
equivalent). It annoys me that I have to import Darwin/Glibc to properly 
convert between standard library types. Would this go with the initialisers 
from FloatingPoint on Integer, or somewhere on FloatingPoint?

Definitely a step up from what we have, and a good foundation to build on.
