You're right, I had it backwards! Thanks for the correction.
Now I'm wondering, could that actually be all that's needed to rescue checked exceptions? Is there any language that has that combination of features?
- gf000 2y agoWell, scala has union types, but it doesn't do checked exceptions per say (but it does have a very advanced type system so similar structure can be easily encoded). I think checked exceptions is pretty rare, so I don't know.. probably some research language (but they often go the extra mile towards effect types)
- int_19h 2y agoBack when Java didn't have lambdas, one of the more advanced lambda proposals (http://www.javac.info/closures-v06a.html http://www.javac.info/closures-v06a.html) had this exact thing for this exact reason. Unfortunately, this take on lambdas was deemed too complicated, and so we got the present system which doesn't really try to deal with this use case at all.
