It's more like I don't need to think about these things. F# gives you immutability by default (but let's you use it if you really need it for a more efficient algorithm) and eliminates nearly all null values. Nulls can still leak in from an RDBMS. Working in an environment like this gets you to if it builds, it works (once you get used to FP thinking). You have to experience it to believe it.
