Without lambda I'd have to create a binder:
boost::bind(&class_name::do_something_sync, this). It's just a bit
more verbose :).
But in a real code there's also another point: usually it's preferable
to use shared_from_this idiom with async functions, to simplify
control over object lifetime.
So it would be either
{
  io_.post(bind(&class_name::do_something_sync, shared_from_this()));
}

or

{
  auto self = shared_from_this();
  io_.post([=] { self->do_something_sync(); });
}

...so the bind version already looks less verbose.
