Hi,
I would to create a list of tuples (or something similar) of invertible
functions
[((a -> b), (b -> a)), ((b -> c), (c -> b)), ....
Such that I could call
forward invertibleFuctionList domainValue = ? -- composite all the functions
backward invertibleFuctionList rangeValue =
forward (reverse invertibleFuctionList) rangeValue -- or something
similar
I would also like to concat them. This sounds like a job for GADT that
someone might have already tackled. Any ideas?
