/**
 * @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 there is no compile-time error if the identifier in
 * a string interpolation construct is the name of type parameter (see
 * Identifier Reference).
