You have labelled arguments or unlabeled arguments, but not *args or **kwargs that you can shove down another function.

In this case, they’re required to be the same type. You can write the code slightly differently to allow them to be independent if you’d like.

For example:

struct Complex<T: SignedNumeric, U: SignedNumeric> {
    var real: T
    var imag: U
}

Nope, not with one generic. You could define a struct with two generic types however.

I’m guessing import Python gets its python libraries (eg matplotlib) from the python environment that was active when you started Jupyter?
