This snippet of code is syntactically valid in both PHP and Java, and produces the same output in both.
/*<?php
//*/public class PhpJava { public static void main(String[] args) { System.out.printf("/*%s",
//\u000A\u002F\u002A
class PhpJava {
static function main() {
echo(//\u000A\u002A\u002F
"Hello World!");
}}
//\u000A\u002F\u002A
PhpJava::main();
/// An operator is given by a list of arities, where each element indicates the number of
/// variables bound by the operator at that position and the length of the list determines the
/// number of variables the operator accepts. The full generalization of arity is called
/// the operator's "valence".
///
/// For example, if I have a little calculator language with let-bindings, its operators
/// would look like this:
///
///
/// enum CalcOps : Operator {
