Playing for PPP for native PHP function overloading

./bin/ppp t1.php #see below for t1.php (and t2.php, required by t1.php)

t1.php

<?php

function abc($s)

// Patchwork\Shim is not a real function but a parser macro
// that takes the replaced function as first arg
// the replacement function as second
// and the parameters signatures (with optional default value/reference)

// Of course these remplacement are useless and for demo purpose only.
// See https://github.com/nicolas-grekas/Patchwork/blob/master/core/compat/bootup.patchwork.php
// for more useful uses of the feature.

Patchwork\Shim(strlen, abc, $s);
Patchwork\Shim(count,  def, &$a = 5);

include "./t2.php";

t2.php

<?php

$var = 'vvv';

echo strlen($var), "\n";
echo count($var), "\n";
echo $var, "\n";
