Heh, allow me to elaborate then. "Let's keep this thing because maybe it
will be useful" is a form of cargo-culting. I am saying that it has no
use, and should be removed, *because* its presence has a cost and no
benefit. Not so much in time, but in code complexity. You can't just
write functions that return values, you have to contort code to store
temporaries and then release and then return. You have to write paired
statements. If you call a user function, you really should set up a
dynwind, which conses, and contorts your code even further.
Array_handle_release is a bad idea.
