I feel that I don't completely understand the question. In PicoLisp, a property list cannot be seen separated from a symbol. After all, these are properties OF a symbol. It is just an implementation detail that they are a list internally. A stand-alone list of key-value pairs is an "association" list, as used with 'assoc' or 'asoq'. > These 'stand-alone' property lists are pretty useful for function > keyword arguments too, e.g. > > ,---- > | (defun foo (&keys a b c (d . 5) e (f .

Is this similar? What exactly would be your goal? ♪♫ Alex -- UNSUBSCRIBE: mailto:[email protected]?subject=Unsubscribe
