Theoretically, yes. But consider complex expressions, that is not something that I would like to do inline

If your Add method took a lambda expression you could have your Count query w/o executing it prematurely. new LinqQueryBatch() .Add( () => posts) .Add( () => posts.Count() ) .Execute(); However, it would possibly cleaner to simply have an execute method that took one or more lambda's to execute. LinqQueryBatch.Execute( () => posts, () => posts.Count() );

Jeff, I agree, but I don't see any other option to do it, frankly. I would have returned an Int32Proxy, but that is not something that is possible :-)

It's a good start. Hmm... Won't "posts.Count()" force posts to be evaluated? It doesn't just wrap "posts" with a new "IEnumerable" which can be evaluated on demand. It really wants to return an "int" immediately. That's the kind of thing I was worried about with Multi-LINQ. I suppose we can define Count() in a non-standard way to return an IEnumerable instead. Looks like that's what you're doing up there actually. Just not sure whether it'll play nice with standard LINQ idioms. (I hope this doesn't turn into another one of those irritating syntax gotchas in C# like with event raising in Rhino.Mocks...)
