Compilation error when proxying a function call via closure #84190

I tried this code:
https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=1478c821bdd7d9e135ef3c752c1e2250

I expected to see this happen: code compiles successfully, just like it does without closure:
https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=bd2d963a5d0241a6272e9a39ac29aa0c

Instead, this happened: compilation error

Changing let to_call = |n| { to let to_call = |n: &mut _| { makes it compile, so this is a duplicate of #41078.
