Flaws

• Not having control flow operators sucks. Especially not being able to return early from a function leads to far too much nesting in common situations where there is a lot of different error handling. But it’s not just error handling for which this is a problem, it’s also annoying when wanting to short circuit some processing in some situations etc.
• Namespacing is a huge problem. The fact that records/variants aren’t scoped to their type name causes name conflicts, and there’s also the problem of commonly conflicting names e.g. catch for IO monad vs catch for Polysemy vs catch for UnliftIO all being different.
