[cfe-dev] using the compiler's method lookup from a clang plugin?

[Noel Grandin via cfe-dev]

It looks like

    void Sema::LookupOverloadedOperatorName(OverloadedOperatorKind Op,
Scope *S,
                                        QualType T1, QualType T2,
                                        UnresolvedSetImpl &Functions)

is the chunk of functionality I need, but how do I call that from a
RecursiveASTVisitor plugin?

In particular, how do I get a pointer to a Scope?

Thanks, Noel Grandin
