I use

  #!/usr/bin/env zsh

most of the time, and no problems with that. The only limitation is
that one cannot pass flags, such as -f. In such a case, one needs
something like:

#!/bin/sh

[ -n "$ZSH_VERSION" ] || exec zsh -f -- "$0" ${1+"$@"}

Now, for Emacs users, a consequence is that Emacs no longer sees it
as a zsh script. I have to put

# local variables:
# mode: sh
# eval: (sh-set-shell "zsh")
# end:

in the script. And in the .emacs:

(add-to-list 'safe-local-eval-forms '(sh-set-shell "zsh"))

If you don't have this, Emacs can add something similar for you
in your .emacs (you will have to confirm, as such eval forms can
be insecure).
