Dear all
Is Queue.fold going over items in the wrong order? It says "equivalent to
List.fold_left" but I would expect the behaviour to be, when inserting items 1,
then 2, then 3 a fold would be given items in that order?
Is there a good reason for this? Could be have a rev_fold for the opposite
order please?
Thanks
Tom
