error: macro expansion ignores token `assert_eq` and any following
--> $DIR/macro-in-expression-context.rs:12:9

LL | assert_eq!("B", "B");

...
LL | foo!()
| ------ caused by the macro expansion here

= note: the usage of `foo!` is likely invalid in expression context
help: you might be missing a semicolon here

LL | foo!();

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