gollark: Spoken languages would just be represented as Haskell ASTs, obviously.
gollark: Does the JVM have tagged unions? No, I do not think so.
gollark: This would have many benefits.
gollark: As a certified idea haver, I have a better idea. We force all languages ever to compile to a common IL which does have all the features people want. There may be resistance to this, which is why it would be deployed via a "trusting trust" attack on all popular compilers simultaneously.
