[INFO] [stdout]    = note: macro invocations at the end of a block are treated as expressions
[INFO] [stdout]    = note: to ignore the value produced by the macro, add a semicolon after the invocation of `_js_impl`
[INFO] [stdout]    = warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
[INFO] [stdout]    = note: for more information, see issue #79813 <https://github.com/rust-lang/rust/issues/79813>
[INFO] [stdout]    = note: this warning originates in the macro `_js_impl` which comes from the expansion of the macro `js` (in Nightly builds, run with -Z macro-backtrace for more info)
