+  template <typename NodeT>
+  CFGMatchSwitchBuilder CaseOfCFGStmt(MSMatcherT<Stmt> M,
+                                      MSActionT<NodeT, State, Result> A) {
+    StmtBuilder = StmtBuilder.template CaseOf<NodeT>(M, A);
----------------



================
Comment at: clang/include/clang/Analysis/FlowSensitive/CFGMatchSwitch.h:67-68
+  template <typename NodeT>
+  CFGMatchSwitchBuilder CaseOfCFGInit(MSMatcherT<CXXCtorInitializer> M,
+                                      MSActionT<NodeT, State, Result> A) {

----------------



================
Comment at: clang/include/clang/Analysis/FlowSensitive/MatchSwitch.h:92-93
+  template <typename NodeT>
+  ASTMatchSwitchBuilder CaseOf(MSMatcherT<BaseT> M,
+                               MSActionT<NodeT, State, Result> A) {
     Matchers.push_back(std::move(M));
----------------
Can we keep doing this?


================
Comment at: clang/include/clang/Analysis/FlowSensitive/MatchSwitch.h:102
 
-  MatchSwitch<State, Result> Build() && {
+  ASTMatchSwitch<BaseT, State, Result> Build() {
     return [Matcher = BuildMatcher(), Actions = std::move(Actions)](
----------------
Ditto.


================
Comment at: clang/unittests/Analysis/FlowSensitive/CFGMatchSwitchTest.cpp:34-35
+struct CFGElementMatches {
+  unsigned int StmtMatches = 0;
+  unsigned int InitializerMatches = 0;
+};
