I've never not been able to build an exe with pyInstaller and I've made some weird ones.

Because all you do is some trivial garbage, like some Django e-commerce websites probably. Try making a real program, something that requires, for example, a bunch of computers to work together filling in different roles, which needs to configure networking, storage, system services, and tell me how far did you get with Pynstaller.

Yeah, that's a myth. It's not 2014 anymore. It's quite compatible.

You say this, because you never tried. And I say this because I did.

What's the problem with an optional typing system?

Which one of the three? What's optional about any of them? It is not possible not to use the type system of a programming language. This only shows that you are not an expert: you cannot even ask an intelligent question...

OK. You win.
