~$ type nice
nice is /usr/bin/nice
There's no way it can know about a zsh function which is
something internal to the shell.
It *executes* a command. So what you think is a builtin is
the command version of it in /bin or /usr/bin:
~$ strace -fe execve nice echo test
execve("/bin/echo", ["echo", "test"], [/* 40 vars */]) = 0
What you could do is:
some-zsh-function & renice $!; fg
Note that it would run that function in a subshell.
