Looking at the responses, on which I can't improve, one might speculate it
was time for someone to implement path searching down in the #! handler for
relative paths.

  #!zsh
  print "Found zsh in $0".

I don't think it has any misfeatures that the env method doesn't have, and
it improves on it in important ways.

This doesn't really touch zsh except that we could do it in our own
#! handler (see zexecve() in Src/exec.c).

(Follow-ups should probably go to zsh-workers).
