This extracts some functions form the ci_lazy_methods operator() whose definition is too long.
I'm not sure about the naming of the extracted function, so please suggest better names if you can.

You might want to document here the fact that is there is no main method it gets all the methods from the main class (and if no main class, all the menthods!)

Possibly GH being weird - but I can't see this method being used anywhere in this PR (or where it is being extracted from?)

Not github's fault, either I lost a commit or the refactoring forgot to replace the old code by a call to this function.
I corrected that.

Document please - I'd expect a filter method to take a predicate

Give default value! Currently if virtual_function_calls is empty it is UB what this returns
