I've inadvertently pressed some send key combo again... simple use of let is fine e.g. (let X 3 do what ever you want to do with X here without much change of hierachy )
Ln doesn't fit this usage pattern and to "let" it be something at the top seems somewhat artificial because there's an if statement deciding whether to change it's supplied value or not.
