// From The Dart Programming Language Specification, section 16.33
// "Identifier Reference":
//
// "A built-in identifier is one of the identifiers produced by the
// production BUILT_IN_IDENTIFIER. It is a compile-time error if a
// built-in identifier is used as the declared name of a prefix, class,
// type parameter or type alias. It is a compile-time error to use a
// built-in identifier other than dynamic in a type annotation or type
// parameter."
//
// Observation: it is illegal to use a built-in identifier as a library
// prefix.

// Dart test for using a built-in identifier as a library prefix.
