&gt;arithmetic in most concatenative languages is written in postfix<p>Postfix? I&#x27;m assuming a typo here but not sure what you meant.<p>Edit: Ah, I&#x27;m guessing it was supposed to be postscript. Makes more sense now.<p>Looks like an interesting language style though, I&#x27;ve been looking for a language that has the bash style piping baked into the language.
