+// ValueType: the bare, nonref version of a type (same as the type for nonrefs).

+// ParamType: what type to pass to functions (refs should not be constified).

+//
+// This set of classes is useful for bundling 0 or more heterogeneous data types
+// into a single variable. The advantage of this is that it greatly simplifies

+// RunnableMethod and IPC::MessageWithTuple.
+//
+// Tuple0 is supplied to act as a 'void' type. It can be used, for example, when
+// dispatching to a function that accepts no arguments (see the Dispatchers
+// below).
+// Tuple1<A> is rarely useful. One such use is when A is non-const ref that you
+// want filled by the dispatchee, and the tuple is merely a container for that
+// output (a "tier"). See MakeRefTuple and its usages.
