Hi Freddy, thanks. Unfortunately, toolz is still not available in the nix-shell. Any Ideas?

In the last lines of your commit-diff, or: 8.10.1.3.1. Develop local package As a Python developer you’re likely aware of development mode (python setup.py develop); instead of installing the package this command creates a special link to the project code. That way, you can run updated code without having to reinstall after each and every change you make. Development mode is also available on Nix as [explained](http://nixos.org/nixpkgs/manual/#ssec-python-development) in the Nixpkgs manual. Let’s see how you can use it. Changing the link to (http://nixos.org/nixpkgs/manual/#development-mode) would fix this.
