One thing I like about `enforce` is that the program's run-time checks
become positive instead of negative statements which I think is a lot

Yes, but that's a minor nuisance. I often do not rewrite conditions by
distributing the negation to avoid this problem. In that case, the
"operation" becomes basically:
if(!(...))
We could introduce a new 'when' keyword:
Perl's unless would "solve" this nicely ;)
