| Classic Lisp list iteration macro, implemented as special form in LabLisp. Expects at least one argument, which must be properly formed list: First element is a plain symbol, which will be the iterator variable. Second element must evaluate to proper list. There might be optional third element, the result form - single expression which will be evaluated after the looping is finished. If there is no result expression, the ''DOLIST'' form returns ''NIL''. | Classic LISP list iteration macro, implemented as special form in LabLISP.
