Like you could indicate if a function was a Enable/Disable actuator and only require the expressed inclusion of the function in definition. For example:

Please show a complete class definition that has a data
member and one of these "endis" functions setting the
data member. Is a getter for the bool also in view?

And then show the declaration of a variable of that class
type with an invocation of one of "endis" functions.

And then, please tell me which constructs are supposed
to be new keywords. And then, please do some research
to show how much existing code that uses those new
keywords in other ways would break.

Thanks,
Jens
