Research direction
Start by running the Rust-like example in the issue and inspect the code responsible for printing closures and formatting negated expressions. Trace how the expression -(3+2) is rendered inside a closure; done means the output preserves the grouping and prints \() = -(3+2) rather than \() = -3 + 2.
