invokeLater() - impossible to refactor@@

Q: if there's a block inside my method, we can wrap an invokeLater() around it -- anon inner class. But is this always possible, assuming local vars are final.

What if a local var must be non-final, but this variable is in the target block? I feel we can create a "final" clone of this variable and use it in the target block.

What if a variable is modified in the target block? I feel we can create a mutable clone and make it a local-var, local to the invokeLater() (actually the run method).

What if a variable is modified in the target block but needed after the block? What if the target block has side effects on local variables?

What if the target block creates objects to be used after the block?
