.. function:: genops(pickle)
- Provides an iterator over all of the opcodes in a pickle, returning a sequence
- of ``(opcode, arg, pos)`` triples. *opcode* is an instance of an
- :class:`OpcodeInfo` class; *arg* is the decoded value, as a Python object, of
- the opcode's argument; *pos* is the position at which this opcode is located.
