some things worth mentioning i observed this bag concept gies (to api) are for example ttl (time to live) or mentioned ability/quality to simply store its state
so for example you could add immediately
some things like movement behind the hood
or whole physics system
i mean
for(...)
DrawDot3D(...)
only alllows to draw
for(...)
AddDot3D(...)
allows for example set ttl *in frames) and after that those dots will automatically vanish (freeing ram and freeing rasterizer burden) which is very nice feature
it gives some kinda new dimension to such api/universe
thats why its worth special mentioning imo
