"Add 'method' to the decorator name when decorating a method" is a pretty simple rule to remember - it's much easier than "Add 'arg_index=1'" (which is a comparatively arbitrary adjustment that requires a fairly in depth understanding of both the descriptor protocol and type-based function dispatch to follow). And you need the change to be explicitly opt-in *somehow*, in order to avoid breaking any existing code that relies on methods decorated with "singledispatch" dispatching on the bound class.
