(Hoping to catch you before you finalize 0.1.12)
Similar to how I felt ceil() was missing from the fundamental math toolset in PICO-8, I feel like there are a couple of fundamentals missing from the table toolset.
Would it be reasonable to add these to the built-in table operators?
function ins(table, index, elem) local temp = elem while temp ~= nil do table[index],temp = temp,table[index] index = index + 1 end return elem end function pop(table) local elem = table[#table] table[#table] = nil return elem end -- (and possibly this alias, just for the sake of being symmetrical with pop) push = add
(Note that I was tempted to suggest an extension to add() where we simply append an optional index, but I've looked at the underlying code you have for add(), and I think the additional code to check for that optional index could slow down existing games too much, so it's probably better to have a new, bespoke ins() function instead.)
With just these two (and a half) additions, it becomes much more intuitive and simple to use tables as stacks, queues, and sets. I think that would be a real boon to both budding and established programmers without really taking the API to a higher level of abstraction.
