I wrote it for use with the *(e::) globbing syntax, where calling out
to an external binary for hundreds/thousands of files is just way way
too slow. eg

#usage, *(e:fattr name:) or *(e:fattr name value:)
function fattr() {
  local val
  zgetattr $REPLY user.$1 val 2>/dev/null
  [[ -n "$val" && ( -z "$2" || "$val" =~ "$2" ) ]]
}
