zsh functions not playing nice.

[Ray Andrews <rayandrews@xxxxxxxxxxx>]

Gentlemen,

I can't get this sort of thing to work:

    $ nice -n 20 some-zsh-function

returns:

   "nice: some-zsh-function: No such file or directory.

I can use 'nice' with any builtin or binary or script, just not with a 
function.
How do I solve that?

Thanks.
