this is even better :) thanks >> 2) special variables >> >> in the "special variables” paragraph i see no mentions of the variable >> $version, but looks like it’s some kind of special, read-only variable, >> because i can screw the shell with this simple line: >> >> function test; set -l version 10; echo $version; end >> >> after defining it all i get is a long list of errors every time i press >> enter. > > If you define a new function called `test`, you're gonna have a bad time. > The shell uses test all over the place - see `help test`.
