+// CDB exposes an "object model" via JavaScript that allows you to inspect debugging info - in this
+// case we want to ask the object model for the return and parameter types for a local variable
+// that is a function pointer to make sure that we are emitting the function pointer type in such a
+// way that CDB understands how to parse it.
