// CONCEPTS:
// Runnable -- A type (really a type class) that has a single Run() method
// and a RunType typedef that corresponds to the type of Run().
// A Runnable can declare that it should treated like a method
// call by including a typedef named IsMethod. The value of
// this typedef is NOT inspected, only the existence. When a
// Runnable declares itself a method, Bind() will enforce special
// refcounting + WeakPtr handling semantics for the first
// parameter which is expected to be an object.
// Functor -- A copyable type representing something that should be called.
// All function pointers, Callback<>, and Runnables are functors
// even if the invocation syntax differs.
// RunType -- A function type (as opposed to function _pointer_ type) for
// a Run() function. Usually just a convenience typedef.
// (Bound)ArgsType -- A function type that is being (ab)used to store the
// types of set of arguments. The "return" type is always
// void here. We use this hack so that we do not need
// a new type name for each arity of type. (eg.,
// BindState1, BindState2). This makes forward
// declarations and friending much much easier.
//
// Types:
// RunnableAdapter<> -- Wraps the various "function" pointer types into an
// object that adheres to the Runnable interface.
// There are |3*ARITY| RunnableAdapter types.
// FunctionTraits<> -- Type traits that unwrap a function signature into a
// a set of easier to use typedefs. Used mainly for
// compile time asserts.
// There are |ARITY| FunctionTraits types.
// ForceVoidReturn<> -- Helper class for translating function signatures to
// equivalent forms with a "void" return type.
// There are |ARITY| ForceVoidReturn types.
// FunctorTraits<> -- Type traits used determine the correct RunType and
// RunnableType for a Functor. This is where function
// signature adapters are applied.
// There are |ARITY| ForceVoidReturn types.
// MakeRunnable<> -- Takes a Functor and returns an object in the Runnable
// type class that represents the underlying Functor.
// There are |O(1)| MakeRunnable types.
// InvokeHelper<> -- Take a Runnable + arguments and actully invokes it.
// Handle the differing syntaxes needed for WeakPtr<> support,
// and for ignoring return values. This is separate from
// Invoker to avoid creating multiple version of Invoker<>
// which grows at O(n^2) with the arity.
// There are |k*ARITY| InvokeHelper types.
// Invoker<> -- Unwraps the curried parameters and executes the Runnable.
// There are |(ARITY^2 + ARITY)/2| Invoketypes.
// BindState<> -- Stores the curried parameters, and is the main entry point
// into the Bind() system, doing most of the type resolution.
// There are ARITY BindState types.
// RunnableAdapter<>
//
// The RunnableAdapter<> templates provide a uniform interface for invoking
// a function pointer, method pointer, or const method pointer. The adapter
// exposes a Run() method with an appropriate signature. Using this wrapper
// allows for writing code that supports all three pointer types without
// undue repetition. Without it, a lot of code would need to be repeated 3
// times.
//
// For method pointers and const method pointers the first argument to Run()
// is considered to be the received of the method. This is similar to STL's
// mem_fun().
//
// This class also exposes a RunType typedef that is the function type of the
// Run() function.
//
// If and only if the wrapper contains a method or const method pointer, an
// IsMethod typedef is exposed. The existence of this typedef (NOT the value)
// marks that the wrapper should be considered a method wrapper.

// The normal type just calls the underlying runnable.

// IgnoreResult(). Normally, if the Runnable's RunType had a void return,
// the template system would just accept "return functor.Run()" ignoring
// the fact that a void function is being used with return. This piece of
// sugar breaks though when the Runnable's RunType is not void. Thus, we
// need a partial specialization to change the syntax to drop the "return"
// from the invocation call.
//
// WeakCalls similarly need special syntax that is applied to the first
// argument to check if they should no-op themselves.
