and something like:

  function _lap { tmp="${(@f)$(whence -pm $1\*)}"; [[ ! -z $tmp ]] && ls -l ${=tmp} }

will produce fewer processes on the way.

Dan.



P.S. I wouldn't know why

  function _lap { tmp=$(whence -pm $1\*); [[ ! -z $tmp ]] && ls -l ${=tmp} }

is not as good, but I'm such a shameless newbie, so it is not that surprising.
