Well, like zsh, and many other improvements on the shell, and gawk and other tooling that doesn't match other awk engines and so forth... you end up having two parallel realities. One for scripting, where you use the bare minimus that is acceptable to run on any server and it's guaranteed to be there, and then your user env where you have all your fun tools.

The cool part is network transparency and forwarding environments and other things that plan9 plays with so that you can work locally, remotely.
