LTerm_dlistMutable sequence of elements (deprecated)
A sequence is an object holding a list of elements which support the following operations:
val remove : 'a node -> unitRemoves a node from the sequence it is part of. It does nothing if the node has already been removed.
val create : unit -> 'a tcreate () creates a new empty sequence
Note: it is OK to remove a node while traversing a sequence
val iter_l : ('a -> unit) -> 'a t -> unititer_l f s applies f on all elements of s starting from the left
val fold_l : ('a -> 'b -> 'b) -> 'a t -> 'b -> 'bfold_l f s is:
fold_l f s x = f en (... (f e2 (f e1 x)))where e1, e2, ..., en are the elements of s
