Then make it so if that's really so disturbing to some dispositions.

(1) Keep the current semantics

t[ k ] = v -- remove 'k' if 'v' happen to be nil, otherwise set it

(2) Add some weird diacritical marks somewhere to signify "store it, I really mean it, and yes, even if it's nil, dammit"

t[ k ] = v! -- set 'k' no matter what 'v' is

Now there is no more 'holes', and all is good and peaceful in the universe. Or something.
