I think you should make a separate bugzilla enhancement request 
(or DIP. I don't know which one's more appropriate) for 
incorporating these better assert messages. It's a separate issue 
from contracts' syntax after all.

I like the fact that we wouldn't need any new 
(comma-separated-booleans) syntax for asserts then.
