I feel like you might be claiming that Haskell does something like Go does, but it actually doesn't: it supports monads, and so uses a monad to hide the error semantics entirely, providing exception-like syntax with automatic propagation. (I might misunderstand your use of "though", though? It could be that you were just noting in passing how Haskell disagrees with all of these supposedly-"modern" languages, and instead leaned into the sane happy path semantics, thanks to monads.) (edit: to be clear, though... I do not think exceptions solve this. I wrote a comment elsewhere on this thread about the semantics issue, but a few other people also wrote similar things while I was trying to type my overly-verbose reply ;P.)
