Fun fact: it's possible in Python. (It tends to lead to segfaults.)

It's not possible in Ruby, but may be achievable using a C extension.
Still, that seems like a very bad idea. I don't know your usecase, but
you could probably either start with an empty array instead of nil, or
"guard" all array methods with "ary ||= []".
