call_user_func_array can return false

[jyggen]

call_user_func_array returns the return value of the callback, or false on error, which means that false could very well be a valid and expected.

Also, cases like \Safe\call_user_func_array([$this, 'someProtectedMethod'], $arguments); doesn't work as expected. Using the native call_user_func_array, the protected method is called as expected, but when using the safe version the method that contains the call to \Safe\call_user_func_array is called instead, resulting in an infinite loop.

Damn it! How could I let that slip through?
There is no proper way to handle errors in call_user_func_array and call_user_func. I cannot possibly deal with protected methods in a proper way.
I'll simply remove the functions altogether from Safe.

Thanks a lot for opening this issue.
