unless(hasAncestor(cxxTryStmt())) should do the work for almost all cases.
Maybe even something like this to catch only valid try blocks
cxxThrowExpr(stmt(forFunction(functionDecl(isNoThrow()).bind("func"))),
unless(hasAncestor(cxxTryStmt().bind("try"),
forFunction(hasBody(hasDescendant(equalsBoundNode("try")))))
+ it should check that the throw is not in CXXCatchStmt (unless it is in
another try block).
