Thanks.
You haven't mentioned the invariant keyword, so perhaps you are
not aware of that feature?

Although the docs seem to favor classes, invariant is available
for structs as well.

How would you resolve the issue I wrote in my first post using
invariants? You cannot add/remove checks from invariants while
using the object. That's what I made different. But there are
still some limits given by the language. Look at point 7 for
instance.
The problem about contract programming in general is you cannot
use it in public library code. Distinction between logic and user
input is a very important thing, we really need to improve this.
You may have noticed that I did not make use of either assert or
enforce. I didn't want to specify this.
