Have to add that we work exclusively in strongly-typed languages. Kinda want to see how it plays out, but I can't help but argue with him, so I think I'll just go.

Considering there is typing in the code why is there no switch to enable type checking at runtime? PHP does this with a per file
declare(strict_types)- why would python be unable to have either a global or per file flag to enable checks?Typing when you need it gives you more freedom over a toggle. You can choose to type some parts of the code while leaving other parts untyped.
For example, if I'm writing a quick and simple Python script I may forgo typing, but when iterating on it I'd go back and add the types I need.
This isn't an issue, though. PHP has the same partial typing flexibility. There are ways to solve that issue and even typed PHP still allows union types including
mixedwhich allows any types.Have you got problems this would solve? I've done a lot of type annotated Python at scale and I can't think of an example.
Edit: given nobody in their right mind allows code that's not checker clean.
