About variadics in Rust

This is an analysis of how variadic generics could be added to Rust. It's not a proposal so much as a summary of existing work, and a toolbox for creating an eventual proposal.

Introduction

Variadic generics (aka variadic templates, or variadic tuples), are an often-requested feature that would enable traits, functions and data structures to be generic over a variable number of types.

To give a quick example, a Rust function with variadic generics might look like this:

from typing import Tuple, List
t = "teen"
y = "ty"
NUMBERS = ["zero", "one", "two", "three", "four",
           "five", "six", "seven", "eight", "nine",
           "ten", "eleven", "twelve", "thir" + t,
           "four" + t, "fif" + t, "six" + t, "seven" + t,
           "eigh" + t, "nine" + t, "twenty"]
TENS = ["thir" + y, "four" + y, "fif" + y, "six" +
        y, "seven" + y, "eight" + y, "nine" + y]

void fragment () {
        vec2 resolution = vec2(1024, 600);
        vec2 texcoord = FRAGCOORD.xy / resolution;

        vec3 colours = vec3(0,0,1);
        float backgroundlight = 0.35;
        vec3 lightcolor = vec3(1,0,0);
