Status as of now: DECIDED: 1. Replace the current outer comment for the new tnum_mul() with a cleaner explanation and the example from the README of the test program. 2. (Related to PATCH 2/2) Drop the trivial tests. UNDECIDED: Instead of just doing tnum_mul(a, b), a) whether to do best(tnum_mul(a, b), tnum_mul(b, a)) b) whether to do best(best(tnum_mul(a, b), tnum_mul(b, a)), best(tnum_mul_old(a, b), tnum_mul_old(b, a))) -- Nandakumar
