Code shuffler moves use keyword after class instantiation

Test case:

<?php
echo "a";
use FooNamespace\BarClass;
echo "b";
BarClass::foo();
echo "c";
echo "d";
echo "e";

Example obfuscated output:

$ yakpro-po --silent --shuffle-statements --no-obfuscate-namespace-name --no-obfuscate-class-name --no-obfuscate-string-literal testScramblerUse.php

<?php
 goto eRjJL; eRjJL: echo 'a'; goto bMybk; jYOQK: echo 'c'; goto RLpd3; s61kw: echo 'b'; goto N2256; N2256: BarClass::U_97n(); goto jYOQK; RLpd3: echo 'd'; goto V30rC; bMybk: use FooNamespace\BarClass; goto s61kw; V30rC: echo 'e';

While the order of execution is correct, PHP actually does not execute the use statement, but interpret it statement-by-statement while generating bytecode for the function. It will select the wrong class for the bytecode and everything will go haywire.

For the sake of completeness, here is a test class which will show that the above code indeed does not run properly. Add an include line for it right after the <?php of each code snippet.

// BarClass.php
<?php
namespace FooNamespace;
class BarClass {
  public static function foo() {
    echo "foo";
  }
}
