You’re lisp syntax is weird but you’re right:
The start argument specified where to start removing things and the end or count arguments specify where to stop removing things (ie at an index or after a certain number of elements respectively).
I claim this is a pretty good argument against the keyword arguments as they don’t necessarily do what one expects.
- tsimionescu 6y agoHonestly, I think the mistake comes from thinking of `remove-if(-not)' as `filter'. When I see code saying (remove-if #'condition '(1 2 3 4 5 6) :start 5 :count 3), I would be pretty surprised if it removed anything prior to the 5th element. :count is worse, just by looking at this code I would not be sure whether it would always remove 3 elements (at most) or if it would remove all elements within a subsequence of 3 elements starting at index 5.
