/**
 * @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.
