Yury, you are really the crazy hacker. Not sure tricks with patching bytecode etc are good for standard library.<div class="gmail_extra"><br><br><div class="gmail_quote">On Wed, Oct 31, 2012 at 11:31 PM, Yury Selivanov <span dir="ltr">&lt;<a href="mailto:yselivanov.ml@gmail.com" target="_blank">yselivanov.ml@gmail.com</a>&gt;</span> wrote:<br>
