error: aborting due to previous error
review comments: modify note wording and change `println` - Don't print the newline on its own to avoid the possibility of printing it out of order due to `stdout` locking. - Modify wording of `concat!()` with non-literals to not mislead into believing that only `&str` literals are accepted. - Add test for `concat!()` with non-literals. 2018-07-15 13:52:11 -05:00			`error: expected a literal`
