Probably by now somebody has already answered this,
but I will share what I discovered.

well, anything in parentheses () will be evaluated immediately
before any function receives the parameter.
If you just type () at the prompt, it returns nothing.
Bu if you do type? () it says unset!

So, you are trying to insert an unset! value into your copy [], an empty block.
I assume the same thing is happening to the change example.
If you are trying to create an empty parenthesis block, then I don't
know off the top of my head how that would look of if it would work.
