Can somebody give me a starting point for understanding varadic functions? I know that we can declare them

I've looked into the formatter, and also the varargs implementation. But it's a bit of a trip through a funhouse full of mirrors. Can somebody describe the basic language approach to non-uniform varargs, and then I can take it the rest of the way reading the library.

Thanks in advance!

there are 3 (or 4?) variadic functions
try
```d
auto foo(T...)(T args){
  static foreach(arg;args){
    ...
```
