/// @assertion It is possible to embed expressions within non-raw string
/// literals, such that these expressions are evaluated, and the resulting
/// values are converted into strings and concatenated with the enclosing
/// string. This process is known as string interpolation.
/// stringInterpolation:
///   '$' IDENTIFIER_NO_DOLLAR |
///   '$' '{' expression '}'
/// ;
/// @description Checks that it is a compile-time error when the identifier in
/// string interpolation construct of the form '$' IDENTIFIER_NO_DOLLAR contains
/// the dollar character that is not a beginning of another string interpolation
/// construct.
