Research direction

Start with the Rust example and its linked Playground, then read the Reference sections covering numeric types, integer method resolution, and type inference. Compare the implicit and explicitly typed tuple cases and determine whether the behavior needs documentation or a linked compiler issue; done means the behavior and expected resolution are clearly recorded.

Written by the indexing model from the issue text.

Description

A-inference

I asked a question on #rust-beginners and it was suggested to make a bug report.

fn main() {
    let implicit = (3, 4);
    let explicit: (i32, i32) = (3, 4);
    let _ = implicit.0.abs(); // fails
    let _ = explicit.0.abs(); // works
}
