No. As perlref says, Only package variables (globals, even if localized) are visible to symbolic references. Lexical variables (declared with my()) aren't in a symbol table, and thus are invisible to this mechanism.

If you want to access lexical variables, you have to do a lot of mucking around with internals. Modules (like PadWalker) can get rid of most of that for you. But I don't think that this module will actually create new lexical variables in the previous scope. Perhaps some module will do it. If not, then I'd bet that it is possible for someone knowledgable to write such a beast.

However actually using it would not be recommended...
