Comment (by SimonKing):
For completeness (with the same definition of `test(T,L,v)` and
`test2(T,L)` as in the previous post):
{{{
sage: T = {}
sage: L = srange(100)
sage: %time test(T, L, ZZ)
CPU times: user 0.53 s, sys: 0.05 s, total: 0.58 s
Wall time: 0.58 s
sage: %time test2(T, L)
CPU times: user 0.67 s, sys: 0.01 s, total: 0.68 s
Wall time: 0.68 s
}}}
Do I understand correctly that your version of `TripleDict` and `MonoDict`
mimics Python's implementation of a dict? Then why is it so much slower?
