> they do have comparable uses, so it makes sense to wish for similar syntax to reduce cognitive overhead
No this makes no sense at all. Set theoretic types don't use special constructors, there is no way to make them look remotely similar. He is clearly not aware that these are different kinds of unions.
> They do.
Nope, precisely because they are less common. You yourself also clearly also didn't understand the difference between "untagged unions" in C and set theoretic type systems.
Uh huh, sure. I didn't know the between a C union and a set theoretic union. I'm just so gosh darn confused, trying to use them set theoretical types in my C all the time!
You have come into a room full of CS practitioners to announce to them that you alone understand what unions are. Never mind fifty years of industry practices and nomenclature - never mind the fact we all already know set theory and unlike you don't confuse set theoretic unions with tagged unions - all that can now be set aside because you discovered set theory last week and now no one understands unions except for you.
Can't wait for next week when you discover some new band, and you'll be in here telling us how no one gets music except for you. :P
