class LListFilter

extends Lens

Filters a list, removing items that fail to matche a predicate. Two predicates must be given in order for putback to work correctly: edits to selected items should propagate appropriately. This propagation is done on a first-come, first-served basis -- the first item of the abstract tree replaces first item that matches pkeep in the concrete tree. If there are more items in the abstract tree than items that match pkeep, then the extra items are added at the end. If there are fewer items in a than those that match pkeep in c, then the last items in c are deleted.
