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:

This is way too narrowly focused to bother with. "Enable" and
"Disable" functions are not nearly common enough (or difficult enough
to write) to add a *language* feature for. You can easily make a
function that takes a bool (or preferably an enum) and call that
