enum within namespace doesn't work in Python

This typescript:

namespace foo {
    export enum bar {
        Zero,
        One,
        Two
    }
}

input.onButtonPressed(Button.A, function () {
    basic.showNumber(foo.bar.Two)
})

converts to this Python:

@namespace
class foo:
    class bar(Enum):
        Zero = 0
        One = 1
        Two = 2

def on_button_pressed_a():
    basic.show_number(foo.bar.Two)
input.on_button_pressed(Button.A, on_button_pressed_a)

with these errors:

Start with the TypeScript namespace and enum example in the issue, then reproduce the generated Python and its errors. Trace the TypeScript-to-Python conversion entry point and compare it with other namespace or enum cases; done means the example generates valid Python and foo.bar.Two works without errors.
