Incorrect "closure bodies that contain statements must be surrounded by braces" error in unrelatedly invalid code

Code

fn test() {
    let value = || {};

    (value;);
}

Current output

error: closure bodies that contain statements must be surrounded by braces

help: try adding braces

2 ~     let value = || { {};

4 ~     (value;});

Desired output

error: expected one of `!`, `)`, `,`, `.`, `::`, `?`, `{`, or an operator, found `;`
 --> src/lib.rs:4:11

4 |     (value;);
  |           ^ expected one of 8 possible tokens

Rationale and extra context

This error is unrelated to the closure, and indeed, applying the suggestion leaves us with:

fn test() {
    let value = || { {};

    (value; });
}

Which now has an improperly closed brace. The correct code would (most likely) be (value)

The original code I had made the suggestion even weirder since the closure was an argument to a Higher Order Function (instead of bound to a variable) and the last line was a function call with a ; after its argument (instead of a paren expression), which happened due to a typo 😅. Just in case something following that structure would make for a useful test case as well:

fn test() {
    let value = std::iter::once_with(|| ());

    std::men::drop(value;);
}
