mountaindew: Good call! Another suggestion I would make is to turn this into an identifier that returns the statement within any fashion, not just a message to a channel. ie: $rev(). Here is an example:

alias rev {
  var %i = 1, %bwOut
  while (%i <= $len($1-)) {
    %bwOut = $mid($1-,%i,1) $+ %bwOut
    inc %i
  }
  return %bwOut
}
