What would be the best way to add support for that ? Adding a new
CXCursor_ExceptionSpec cursor, which has child cursors of of some
appropriate reference kind ? Or a query function that gives the
equivalent information explicitly ?

If you need type- and value-dependence information, I suggest adding clang_isTypeDependent()/clang_isValueDependent() that operates on expression cursors.
OK, understood. I think what I was trying to ask is for
CXType_Unexposed, not CXCursor_UnexposedDecl.
template <typename T>
would report a FieldDecl cursor for 'member'. When calling
clang_getCursorType() on that, I obtain a CXType_Unexposed, while I
think something more indicative of this being a dependent type would be
more useful. (If that is not possible, a new clang_isTypeDependent()
function would certainly be helpful.)
