Two disappointments I have with K&#x2F;Q is that<p>1) functions that take multiple arguments break the pattern of concatenating functions to build advanced expressions (yes, there is . but it&#x27;s not nice to use)<p>2) the right to left evaluation means you constantly have to go back to the begin of the line to append functions<p>Both of these problems go away if you make it a stack based language with postfix notation.
