> Is that different from contracts?
It's an expansion of contracts. AFAIK, One can define in SPARK whole compilation units, whose only purpose is to help writing contracts, for arbitrarily complex dynamic or static checking.
The principle is, with a specific assertion policy, anything marked with the GHOST aspect would disappear from the code (and object code), but the program would be functionally identical.
.. One thing I found (a bit) irritating from a beginner point of view, is that normal visibility rules still still holds in contracts/assertions. It would be much easier to write contracts about conditions of (at least) things declared in the private part. It would be nonsensical to let them reach the body though, that I can understand. But why not packages' private part ?
