/// @assertion An expression statement consists of an expression other than a
/// non-constant map literal that has no explicit type arguments.
/// The restriction on maps is designed to resolve an ambiguity in the grammar,
///   expressionStatement:
///     expression? ‘;’
///   ;
/// Execution of an expression statement e; proceeds by evaluating e.
/// It is a compile-time error if a non-constant map literal that has no explicit
/// type arguments appears in a place where a statement is expected.
/// @description Checks that it is not a compile-time error when a map literal
/// with explicit type arguments or a constant one is used as a statement.
