in any case, since a pair of Int64's is not a clear win and an Integer definatly is a clear win in terms of usability then I believe we should go for that.
It's a radical idea but... Maybe we could avoid all these issues by using an abstract type with all sensible instances (including Num though it is only semi-sensible for times).
Internally, we might use Integer or two Int64s or we might even add Int128 to our compilers. Externally it looks like an Integral (or Fractional?) type.
Yes, I think that's a reasonable compromise. The accuracy is still specified to be picoseconds, but the representation is hidden. Any objections? Cheers, Simon
