/// @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 the identifier is parsed in a greedy manner and the
/// entire substring from the '$' character to the first non-identifier or '$'
/// character is used, even if there're shorter matches for lexically visible
/// identifiers.
