/// @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.

/// @description Checks that it is a compile-time error when the identifier in
/// string interpolation construct of the form '$' IDENTIFIER_NO_DOLLAR starts
/// with the dollar character.
