that might be an undersell. We do full derivation tree's, as per prolog. But we take this a step further, and have fully reactive derivation trees - which most prolog systems does not have.

The prolog features we do not have are:
cut
List unification.
Unbound properties  for fact instances. So that it unifies against the property.
Expressions for arguments in unifications.
