 I thought this feature would be useful in the bindings, but it turns out
 it isn't, since we always also need something based on the class name too
 (and not just the C++ classname as a string literal, which we can
 efficiently get from the error object).

 But I'd implemented it before I realised that, so here's the patch in case
 we decide it is useful generally, or find a way to use it in the bindings.
