            Bug ID: 20101
           Summary: clang::ExprIterator and clang::ConstExprIterator do
                    not satisfy an iterator concept
           Product: clang
           Version: trunk
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Frontend
          Assignee: unassignedclangbugs at nondot.org
          Reporter: felip_assis at hotmail.com

    Classification: Unclassified

It seems that clang::ExprIterator and clang::ConstExprIterator are intended to
be random access iterators, but they cannot be used with standard library
algorithms.

This is because they lack typedefs (iterator_category, value_type, etc.) as
well as definitions for post-increment, pre- and post-decrement, operator<,
operator<=, operator+=, operator-=, and operator+ with difference type as first
argument.
