A technique I use to quickly test an idea is to have a dummy "test" method that calls a method I'm working on. Used in conjunction with NCrunch, and Console.WriteLine(), I can make changes to the method and immediately see the results without having to save/recompile/run (continuous testing).

I think it would be great if LInqPad also allows for this kind of cycle. Being able to see the progress of a script without have to stop and run every time making a change can be a huge productivity booster - especially when incrementally building an algorithm.

I think it would make sense to only enable this on a per query basis.
