How to make zip work with more than 6 elements?

Start with the Zip::from, .and, and .for_each entry points and the compiler example at src/main.rs:47. Review how support for the existing producer counts is organized, then verify that the seven-producer example compiles and executes with the expected values.

I want to use zip (or azip!) with 7 producers but its only implemented for max 6 producers. Is there a convenient way to also implement it for more producers?

Minimal Example Code:

let v1: Array1<i32> = Array1::zeros(3);
let v2: Array1<i32> = Array1::zeros(3);
let v3: Array1<i32> = Array1::zeros(3);
let v4: Array1<i32> = Array1::zeros(3);
let v5: Array1<i32> = Array1::zeros(3);
let v6: Array1<i32> = Array1::zeros(3);
let v7: Array1<i32> = Array1::zeros(3);
Zip::from(&v1)
	.and(&v2)
	.and(&v3)
	.and(&v4)
	.and(&v5)
	.and(&v6)
	.and(&v7)
	.for_each(|v1, v2, v3, v4, v5, v6, v7| {
		println!("{}, {}, {}, {}, {}, {}, {}", v1, v2, v3, v4, v5, v6, v7);
	});

Error:
