[cfe-dev] UsingShadowDecl everywhere?

[Craig Silverstein]

} Shadow declarations should only show up in "found" declarations,
} which I think are only ever stored as part of a DeclAccessPair.
} Otherwise we should already have looked through the shadow decl.

Is there a way to summarize how they might be exposed through methods
on AST classes?  Like would redecls_begin()/end() show a using shadow
decl?  I don't see DeclAccessPair as part of the API for AST nodes, so
I'm guessing this is at a layer that's hidden from end users (like
myself).
