RuntimeException : AspectMock couldn't parse some of files.

I've got this error with such code (originally from Twig library):

if (function_exists('mb_convert_encoding')) {
    function twig_convert_encoding($string, $to, $from)
    {
        return mb_convert_encoding($string, $to, $from);
    }
} elseif (function_exists('iconv')) {
    function twig_convert_encoding($string, $to, $from)
    {
        return iconv($from, $to, $string);
    }
} else {
    function twig_convert_encoding($string, $to, $from)
    {
        throw new Exception('No suitable convert encoding function (use UTF-8 as your encoding or install the iconv or mbstring extension).');
    }
}

With such code I get this error (I'm using AspectMock library, but as I understand, this exception is thrown from Go! library):

RuntimeException : AspectMock couldn't parse some of files.
 Try to exclude them from parsing list.
There were following reasons for this exception:
Thrown when working with file "{root}\src\ProxyBundle\ProxyBundle.php" token stream.
The cause of the exception was the } token (line 29) in following part of \ProxyBundle source code:

 24: 
 25: } elseif (function_exists('iconv')) {
 26:     function twig_convert_encoding($string, $to, $from)
 27:     {
 28:         return iconv($from, $to, $string);
*29:     }
 30: } else {
 31:     function twig_convert_encoding($string, $to, $from)
 32:     {
 33:         throw new Exception('No suitable convert encoding function (use UTF-8 as your encoding or install the iconv or mbstring extension).');
 34:     }

Hello, thank you for the issue report, however this is not a bug for go-aop-php :) I'm using php-token-reflection to perform static analysis of source code and it can not handle dynamic definition of functions like this one. This is a known issue, my suggestion is to add this file to the blacklist in the kernel.

Ok then. I already added while twig library to a blacklist. Thanks
