// The generated file contains four major function templates
// (in variants for arbitrary numbers of arguments up to 10,
// which is why it is machine generated). The four templates
// are:
//
// WrapRunnable(o, m, ...) -- wraps a member function m of an object ptr o
// WrapRunnableRet(o, m, ..., r) -- wraps a member function m of an object ptr o
// the function returns something that can
// be assigned to *r
// WrapRunnableNM(f, ...) -- wraps a function f
// WrapRunnableNMRet(f, ..., r) -- wraps a function f that returns something
// that can be assigned to *r
//
// All of these template functions return a Runnable* which can be passed
// to Dispatch().
