I've not tried for a while but just getting that to even compile was a nightmare. It seemed to be a fork of the Python 2 code base. They've done the right thing by having a POSIX compatible layer but I completely disagree with their idea of what is wrong with the existing Bourne syntax and needs changing. An interactive shell needs to keep special characters to a minimum and stick to commands as the basic unit on which things are built. Zsh is already able to correct many of the worst elements of the Bourne syntax.
