A closely related issue: fromIntegral is in Integral which also

the two are semantically quite disjoint. I can *easily* see the
semantics of fromIntegral
on EpochTime, but not the semantics of quotRem on EpochTime.
Having fromIntegral
would solve the above puzzle... :)
As I understand it, it's widely recognised that Haskell's current
numeric class hierachy is broken (or at best, not very well chosen), but
nobody came up with a better suggestion yet.
(By all means, somebody correct me if I'm wrong here...!)
Also, that hierachy is in the Haskell Report, so we'll have to wait for
Haskell' to fix it for good. (Although you can roll you own right now -
if you can think of a better design...)
