/**
 * @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.
 * STRING_INTERPOLATION:
 *   '$' IDENTIFIER_NO_DOLLAR
 *   | '$' '{' Expression '}'
 * ;
 * @description Checks that there is no compile-time error if the identifier in a string
 * interpolation construct is the name of type parameter (see Identifier Reference).
