Well, they are algorithm-specific. With Qi4j the algorithm becomes a Mixin with a bunch of Properties as Parameters. But the algorithm isn't exposed to the execution context per se, as it is of relevance. > Maybe more generally, I think I might be looking for something like "const" > keyword in C++.

On one hand you can place the mutable and immutable methods in separate interfaces and pass one or the other (or "both") around. The other way is the brand new feature of 'multiple types for entities', which allows more than one interface per Entity instance. > I hope I am not asking for too much.

Yes it is not open-source, but that is not the main reason, since sharing some snippets isn't a big deal. But I have not done enough 'coding' on it yet, mostly just drawings on paper and whiteboard. And I am also on the road (currently in Berlin, soon to Prague) and don't have enough time on these things right now.
