[cfe-dev] TraverseExplicitCastExpr?

[scott constable via cfe-dev]

I figured out the problem myself. Traverse* only hits the base class of
each node (e.g. Decl, Stmt, or Type), and the dynamic class of each node.
Since ExplicitCastExpr is abstract, TraverseExplicitCastExpr is not valid.
Instead I needed to use VisitExplicitCastExpr.
