dynamic call to method with out/ref arguments is not implemented

[jakubmisek]

calling methods dynamically with ByRef argument is not handled properly, resulting in run-time exception.

this happens only in some cases, this feature seems to be implemented already for PHP-like functions already implemented when a function argument is a PHP-like PhpAlias.

public class X {
  public void test( out Dictionary<string, string> d) {
    d = new Dictionary<string, string>() {
      { "a", "b" },
    };
  }
}

<?php
// $unk = new X; 
$unk->test( $d ); // exception at run time
print_r( $d );

• [x] do not load full value for out arguments
• [x] dynamic write-back mechanism (already impl. at compile time)
• [x] write back to local variable
• [x] write back to global variable
• [x] write back to an array item or property (runtime chain), only expect PhpValue/PhpAlias
• [ ] write back to "runtime chain" targeting other types than PhpValue/PhpAlias
• [x] out/ref parameter not provided (do not crash, ignore)
