Extended list. Maintains a dictionary for faster lookups (optionally keeps hash of item object representation by marshalling) and with some operator overloading can perform mathematical operations among instances.
from collections import MutableSequence
import marshal
from operator import add, div, mul, neg, mod, sub
from operator import ge, gt, le, lt, eq
from itertools import imap
'''
Extended list class
- fast lookups by maintaining a dictionary with the values
- numeric operations between 2 instances are possible (like Octave matrices)
