10:57 Design #377 (In Progress): IsDivisible -- exact semantics?
The problem with dividing @4/2@ in @ZZ/6@ is that the true answer is @2@ in @ZZ/3@ -- a different ring! The answer ... John Abbott

While dealing with issue #248 I realised that the exact semantics of @IsDivisible@ are not clear.
The problem is whe...

17:38 Feature #312: LongRange(a,b) returning vector of long a..b (included)
It might be worth moving the impl into its own *separate file*: this would remove the need to include @vector@ in the... John Abbott
