Please also change the `EnterExpressionEvaluationContext` in `TreeTransform::TransformTemplateArgument` to specify `EK_TemplateArgument` (though that doesn't actually matter for the lambda diagnostics because we'll find all the problems in the template definition context). Then this LGTM. Thanks!



================
Comment at: include/clang/Sema/Sema.h:984
+    enum ExpressionKind {
+      EK_Decltype, EK_TemplateParameter, EK_Other
+    } ExprContext;
----------------
Should `EK_TemplateParameter` be `EK_TemplateArgument`?
