Yes and no. There are so many aspects in the implementation (some of 
them I mentioned in earlier) that make any approach completely useless 
if they're not considered and thought about very deeply. And: I'm afraid 
that are very complicated things.

Sorry to say that, but creating 'something' that is influenced a WG21 
proposal by isn't the right way here, it's *really* just waste of time!

As I tried to explain before, the only useful thing to do in this field 
I can imagine is an arbitrary length integer implementation that can 
later be used to implement a decimal class. I promise, it will be 
complex enough to encapsulate the integer encoding for all platforms, 
and once when such aspects are resolved, any other work is welcome, too!
