What type are they?

  Depends on what you assign to these variables. fn main() { let (a, b, c); a = true; b = [1]; c = "foobar"; } https://play.rust-lang.org/?gist=ebedd0cd5b6707410aff&version=stable https://play.rust-lang.org/?gist=ebedd0cd5b6707410aff&versio...

    That's my problem. YOU can't tell. You cannot just look and see what is going on.

      Sure you can, it's pretty clear that a is a boolean, b is an array on the stack and c is a string. If the code is so complex you can't eyeball a local scope you probably have bigger problems than whatever the type of the variables are, and if you get one wrong the compiler will yell at you.

  Whatever type the compiler infers based on the assignments you make afterwards (and a compilation error if there isn't any/enough information to infer the type).
