Living in a World Built on the Following Axioms...

u + (v + w) = (u + v) + w

u + v = v + u

v + 0 = v

v + (- v) = 0

a (b v) = (a b) v

1 v = v

a (u + v) = a u + a v

(a + b) v = a v + b v

lazy evaluation

In Container Emulation in Python I showed how easy it is to emulate container behavior in Python in order to enable concise data access. In this post I want to talk about how this can be accomplished lazily.
