09:42 CoCoALib Feature #1743: Implement Truncated GBases for homogeneous input

Is it worth putting the ex-bug (mentioned in comment 6 above) as a genuine exbug test?
John Abbott

09:40 CoCoALib Feature #1742: MinGens could be faster

Could we put here a couple of test cases?
I think the "fancy" phrase is "regression testing": make sure the some fut... John Abbott

How to compute the GCD of x^e1 * g1(x^d1) and x^e2 * g2(x^d2)?
Is it just x^min(e1,e2) * gcd(g1(x^D1), g2(x^D2))[x... John Abbott

11:16 CoCoA-5 Design #610 (Closed): Variable It: assign before or after printing

Current behaviour is acceptable (and should still be safe even if we make printing interruptible).
Closing.

I'm still with *won't fix* because we have far more important things to do with our time.
Reject?
