1. Inheritance with contracts is evaluated in a special way, 'in contracts' in the base and derived method (property) are or-ed, so if one of them passses, the contract is believed to have succeeded. As you don't have a contract in the base-method: "@property void width(int width)", I think that the compiler assumes that its empty contract is always true.

Doesn't sound right to me. "Or"ing contracts with different inherited methods can't possibly be a feature. I'll create a bug report for it.

Hi Mikey,
It's the way DbC (Design by Contract) works, have a look at point 8 in https://www.eiffel.com/values/design-by-contract/introduction/
