        It also doesn’t have throw/try/catch. If a function can fail, it returns a Result and you have to deal with the failure case explicitly.

          Yeah it’s a bit inaccurate to say it’s not supported. It just has edge case handling written explicitly into whatever thing you’re building (I assume it’s required to do so in order to be well-typed). It took this idea from Haskell, which might have gotten it from Miranda or something.

            I like the pattern a lot more. It makes you just initialize the value and only keep it ‘nullable’ for where it’s needed and then you need to check. Even .net implemented it (but a bit more awkward)
