Description
The enum com.sun.source.tree.Tree.Kind should have a method
like this:

public Class<? extends Tree> asInterface();

Conversely, a method like this might also be convenient:

public static Tree.Kind asKind(Class<? extends Tree> clz);

This should also be considered for JSR 269.

EVALUATION mapping is many-1, so forward map is well defined and easy enough; reverse map is not well defined. Given the forward map, it would be easy enough for clients to invert it with whatever semantics they desire when there is more than one kind for an interface class.

EVALUATION A good idea.
