While doing some work with nullable types in .NET 2.0 (a very nice feature overall), I ran into a very annoying limitation of System.Nullable: It doesn't implement IComparable or IComparable. Don't know how I missed this one before!

I guess I can understand why it doesn't, but, in retrospect, I would've preffered Nullable had constrained T so that it could implement the comparison interfaces properly particularly since 99% of the types you'd use Nullable with anyway already support them (meaning all primitive value types in the framework and the rest of the pretty basic ones).

Oh well, live and learn...
