It should just work in the next release :). There are problems with it right now but I checked in a fix to make this work last week.

That is disturbingly easy. I knew you'd know the answer.
But I wonder if that would work for removing a handler from an event?
someObj.someEvent += objOps.ConvertTo<DelegateType>(obj);
someObj.someEvent -= objOps.ConvertTo<DelegateType>(obj);
One workaround might be to cache the delegate on the way in and use
the cached delegate to remove it.
_cache[obj] = objOps.ConvertTo<DelegateType>(obj);
someObj.someEvent += _cache[obj]
someObj.someEvent -= _cache[obj]
But maybe there's a better way, or maybe I'm daft and it'll just work.
