Rust syntax: assignment to underscore without let

For a few Rust versions now, one can do _ = foo() instead of let _ = foo() in assignments. However, I can not recall the name of this syntax and can't find official documentation for it. I also don't find the PR in the rustlang repo. Can anyone provide some context, please?

It is part of the destructuring assignment RFC, that allows pattern to be used for assignments and not just variable declaration. Stabilized in Rust 1.59.0.
