Maybe I misunderstand your question. As a Lua coder, when I assign nil
to something, I expect the former value to simply be deleted (assuming
no other references). Would it not be better to write a 'clear' method
that does what you want?

I believe what you've missed is a recent thread requesting a
table.wipe function to the C API that could wipe a table more
efficiently than iterating over the contents and nil'ing out every
entry. This appears to be a request for functionality in this proposed
function.

I did see that thread, but when Andrew says "When someone sets the list
to `nil`, i need to clear it.", it sounds like this:
local list = createListAndFillItWithStuff()
-- This magically clears the table, not the variable.
list = nil
I don't see how else to interpret his question.
