 // Omitting the following import is an error:

It should look like:
  /// 01: runtime error, static type warning

Since it will give a valid warning when running dartanalyzer on it (but double
check in the spec that it's supposed to give a warning [and not an error]).

unresolved identifiers are warnings.
thanks, and done.
