So why not define a FixedPoint class, based on Integer, with all the 
operations and #coerce? It will be more efficient (and simpler) than 
decimal float, and Float can remain IEEE float, which is what most 
numerical libraries use anyway. Perhaps this suggestion would be more 
acceptable if there were a literal notation for fixed point? What about 
"_123.45" for 12345/100?

Food for thought:
