 * would still work without any stack errors), but there are some constructs
 * that limit jumping:
 *
 *  o Lines with an 'except' statement on them can't be jumped to, because
 *    they expect an exception to be on the top of the stack.
 *  o Lines that live in a 'finally' block can't be jumped from or to, since
 *    the END_FINALLY expects to clean up the stack after the 'try' block.
 *  o 'try'/'for'/'while' blocks can't be jumped into because the blockstack
 *    needs to be set up before their code runs, and for 'for' loops the
 *    iterator needs to be on the stack.
