If lexical variables are already declared in the calling package, you can change their value, e.g. with PadWalker.

Otherwise it wouldn't compile under strict if you try to use them.

    Declaration can be worked around using parser hacks. That's what Object::Util does. It declares and populates lexical variables for the caller. (Though it falls back to package variables if it's unable to do the parser hacking stuff.)
