// This test ensures that if there is are any macro calls alongside a `main` function,
|
|
// it will indeed consider the `main` function as the program entry point and *won't*
|
|
// generate its own `main` function to wrap everything even though macro calls are
|
|
// valid in statement contexts, too, and could just as well expand to statements or
|
|
// expressions (we don't perform any macro expansion to find `main`, see also
|
|
// <https://github.com/rust-lang/rust/issues/57415>).

// See <./main-alongside-stmts.rs> for comparison.
