I have implemented in CTFE, what I'd like asserts to look like:

It prints at runtime:

with x: 2, y: 3

When you write a contract like this:
void foo(uint x, uint y)
in { mixin(q{ x > y && x < 10 }.holds ("x must be a digit and
larger than y")); }
body { … }

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.
