Would an other wording fit also?

The returning of a boolean value should just work. Can the reference to
the C programming language be lifted already if an external script processor
will finally take care for the embedded source code?

I imagine that there will be more dependencies to consider, won't it?

Would it make sense occasionally to execute the predicate function
in parallel (by a dedicated thread or another background process)?
