Thanks for that analysis.  So we have a bool that is neither a 
boolean nor a bit.  That stinks.

Walter and Andrei have made their decision, so it doesn't look 
like we'll be able to do anything about it unless maybe Atila 
feels that it's something that needs to be addressed.

Anyway, I'm of the mind that the language should just provide a 
set of powerful, composable primitives and delegate 
course-grained features and specializations to the library.  I've 
been re-imagining druntime and phobos at lot lately and I'm more 
confident that we can define a wrapper around `bool` to give it 
proper boolean semantics.  Maybe, if Walter would support it, we 
could then fix bool to make it a proper `bit`.  Then in the 
library `alias bit = bool;` and live happily ever after.

If anyone's looking for a challenge, I welcome them to propose a 
new `Bool` type (note the capital B) for inclusion in my new
