Another VOC milestone

class MyStringAnalog(implements=java.lang.CharSequence):
    def __init__(self, value):
        self.value = value

    def charAt(self, index: int) -> char:
        return 'x'

    def length(self) -> int:
        return len(self.value)

    def subSequence(self, start: int, end: int) -> java.lang.CharSequence:
        return MyStringAnalog(self.value[start:end])

    def toString(self) -> java.lang.String:
        return self.value


from java.lang import StringBuilder

builder = StringBuilder()

builder.append("Hello, ")

analog = MyStringAnalog("world")

builder.append(analog)

print(builder)

Should charAt not return self.value[index]?
