Checks the bytecode of *frame* to find the name of the variable a result is |
being assigned to and returns that name. Returns the full left operand of the |
assignment. Raises a #ValueError if the variable name could not be retrieved |
from the bytecode (eg. if an unpack sequence is on the left side of the |
assignment). |
