           Summary: CIndex should implement iteration based interfaces for
                    cursors
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: AST
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: daniel at zuster.org

Currently CIndex implements a callback interface for visiting the children of
cursors, with some helper features to recurse / break the visitation. This may
be "handy" for C, but it is cumbersome as an API for wrapping in other
languages, especially ones which have decent iteration support. It would be
nice to support an iteration interface which exposed an actual iterator object.
Clients can then implement whatever traversal scheme they like, and wrap it in
helper methods if need be.
