No, it isn't:
$ which ls
/bin/ls
$ type ls
ls is /bin/ls
Compare to
$ type ll
ll is an alias for ls -al
$ type dir
dir is a shell function from /home/wiz/.zshrc
But I take back the statement that it works with /bin/ls in the dir
function definition, it shows the same broken behaviour. Not sure why
I thought it worked before, sorry for that red herring.
