Now I understand, I didn't consider not to tell rev how many sub
arrays there would be. I have no clue when this would be useful
though, maybe you can explain that?
At first I wanted to write an example function that uses the
paramCount, so it would automatically fill the array in a switch (at
some point you do know what the max subarray count would be). But
that'd be way too complex, and you'd need one for putting, and one for
getting, so they'd suddenly be a kind of strange cprops. Using do is
certainly the simplest way, but if you really care for speed, maybe
such a function could be useful, despite the complexity?
This is a rather interesting topic to me :D
