No; by using an array with a nil in it, you're breaking the rules, and
you're open for all kinds of undefined behaviour.

I believe this also applies to unpack({...}), assuming that ... is
syntactic and not shorthand for 'insert stuff here'. If the ... expands to
a tuple containing a nil, Bad Stuff will happen.
