Because mixing types in an array is stupid enough that I thought it might just not be valid.
Mixing types in an array/list is not remotely stupid. How exactly would you suggest expressing the lack of a value in a series of numbers without None/null? There's your mixed types. Don't let weird dogma get in the way of practicality.
Since Codon performs static type checking ahead of time, a few of Python's dynamic features are disallowed. For example, monkey patching classes at runtime (although Codon supports a form of this at compile time) or adding objects of different types to a collection. This seems like a very different language from Python if it won't let you do: [1, 'a string']

That's an Optional[int]. It's not "mixed types", it's a union type.
