I hesitate to modify the inheritance structure of Clojure's
interfaces.
ClojureCLR does follow ClojureJVM in providing support for these
interfaces in the abstract base classes underlying things such as
PersistentTreeMap.
In ClojureCLR 1.3-alpha:
public class PersistentTreeMap : APersistentMap, IObj,
Reversible, Sorted, IEnumerable<IMapEntry>,
IDictionary
public abstract class APersistentMap: AFn, IPersistentMap,
IDictionary, IEnumerable<IMapEntry>,
MapEquivalence,
IDictionary<Object,Object>
The only difference in 1.3-alpha versus 1.2 is that 1.3 adds the
generics IEnumerable<IMapEntry> and IDictionary<Object,Object> for
interop with System.Linq and related libraries. 1.2 does have the
IEnumerable defined. The entries iterated are IMapEntry.
So you should be able cast directly to IEnumerable in either version,
without casting to PersistentTreeMap.
