I am playing with the current dev version Q 2.6/ e. g.:q)l:(1;;3)q)lplist(1;;3)q)l[0]1 0 3q)count l1/ the same when in K:q)\ l:(1;;3) lplist(1;;3) l[0]1 0 3 / all the above behaves differently if no nil was tried to beincluded:q)m:(1;2;3)q)m1 2 3q)count m3/ however, with an older version of K, 2.95: l:(sym;1;;4.5) l(sym;1;;4.5) l[0]`sym
