At the time of that objection, I did not realise that "time" already
required Rank2. My preference would be for "time"s dependency on
ReadP to be removed in favour of a H'98 parsing combinator library,
thus bringing "time" back to true portability.
(Back in the autumn, I did spend some time attempting to re-code
"time"s parsing code precisely to remove the ReadP dep, but never
However, you might consider that a step too far, in which case adding
the Rank2-requiring Data instances into "time" might be the better
solution for you.
