Definitely but that gurantee is thrown away the moment you pull a 3rd party black box in.

I'm suggesting it's feasible but not necessarily perfect and when it does go boom, which it does when you have 100 million HTTP hits a day, you need to be able to find out precisely where it went wrong. LINQ makes that damn hard:

   NullReferenceException
   Company.Product.Assembly.Namespace.Type.Method() +14
   ...

When line 14 has 22 dereferences then you have no idea why it broke.
