-`fn main()` or the specified start function is not allowed to be
-async. You might be seeing this error because your async runtime
-library is not set up correctly.
+The entry point of the program was marked as `async`.
 
 Erroneous code example:
 
 ```compile_fail,E0752
-async fn main() -> Result<i32, ()> {
+async fn main() -> Result<i32, ()> { // error!
+    Ok(1)
+}

+`fn main()` or the specified start function is not allowed to be `async`. You
+might be seeing this error because your async runtime library is not set up
+correctly. To fix it, don't declare the entry point as `async`:
+
+```
+fn main() -> Result<i32, ()> { // ok!
     Ok(1)
 }
