error: expected expression, found `;`
--> $DIR/issue-109237.rs:2:12
|
LL | () => {;};
| ^ expected expression
...
LL | let _ = statement!();
| ------------ in this macro invocation
|
= note: the macro call doesn't expand to an expression, but it can expand to a statement
= note: this error originates in the macro `statement` (in Nightly builds, run with -Z macro-backtrace for more info)
help: surround the macro invocation with `{}` to interpret the expansion as a statement
|
LL - let _ = statement!();
LL + let _ = { statement!(); };

error: aborting due to 1 previous error
