Comment (by darij):
Is this a reasonable speed test?
{{{
sage: R = PolynomialRing(QQ, 'x')
sage: Q = QuadraticForm(R, 3, [1,2,3,4,5,6])
sage: Cl.<x,y,z> = CliffordAlgebra(Q)
sage: d = {(0,1): R.gens()[0], (1,2): R.zero(), (0,2): R.one()}
sage: %timeit Cl._from_dict(d, remove_zeros=True)
100000 loops, best of 3: 5.32 µs per loop
sage: l = (((0,1), R.gens()[0]), ((1,2), R.zero()), ((0,2), R.one()))
sage: %timeit Cl._from_dict({m: k for (m, k) in l if k != 0})
10000 loops, best of 3: 23.8 µs per loop
sage: %timeit Cl.sum_of_terms(l, distinct=True)
100000 loops, best of 3: 7.36 µs per loop
}}}
(I've misnamed the variables but this shouldn't matter...)
Where should the unshuffle go?
