Weird error messages when I miss to define macro name.

[fortune0502]

Code

macro_rules! {
    () => {};
}

Current output

error: cannot find macro `macro_rules` in this scope
 --> src/lib.rs:1:1
  |
1 | macro_rules! {
  | ^^^^^^^^^^^
  |

Desired output

error: missing name for `macro_rules!`
 --> src/lib.rs:1:1
  |
1 | macro_rules! {
  | ^^^^^^^^^^^
  |

Rationale and extra context

I am wondering if I should import something to use macro_rules! inside lib.rs.
The error output shows that rust compiler doesn't recognize macro_rules! macro so it should be imported from anywhere else.
