Unable to access the parameters of super class reactor

Parameters of the superclass cannot be accessed in the sub class reactor's top-level statement.
For example, the following example uses it as an argument of timer.

target Python;
# super class
reactor GeneralController(control_period = 100 ms) {
    reaction(startup) {=
        print(f"hello")
    =}
}

reactor PIController2 extends GeneralController {
    # error , Accessing super class's parameters in reactor
    timer t(0, self.control_period) # with self
    reaction(startup) {=
        print(f"hello")
    =}
}
reactor PIController3 extends GeneralController {
    # error , Accessing super class's parameters in reactor
    timer t(0, control_period) # without self
    reaction(startup) {=
        print(f"hello")
    =}
}

Errors provided by lfc are as follows

This problem does not occur for access within a reaction.

target Python;
# super class
reactor GeneralController(control_period = 100 ms) {
    reaction(startup) {=
        print(f"hello GenCtr:{self.control_period}")
    =}
}

# no error: Accessing super class's parameters in reaction
reactor PIController1 extends GeneralController {
    reaction(startup) {=
        print(f"hello Ctr1  :{self.control_period}")
    =}
}

This code can be executed without error

@cmnrd and @edwardalee, this looks like it should be valid code:

reactor PIController3 extends GeneralController {
    # error , Accessing super class's parameters in reactor
    timer t(0, control_period) # without self
    reaction(startup) {=
        print(f"hello")
    =}
}

I suspect that the C target has the same problem.

Yes, there should be no self.
