I work in Java every day and I'll take exceptions any day over... that. I have a lot of respect for the engineering work the Go team put into the compiler, tool

  When it comes to error handling I rank things along a spectrum: Enumerated Types > Checked Exceptions > Error values > Unchecked Exceptions. The spectrum I'm ranking on is how much assistance the compiler gives me in ensuring I am aware of the error. Java has support for the second best option but culturally avoids it like the plague. Go has support for the third best option and culturally leans hard into it. C# and Python are ranked strictly at the bottom. The preference in many language communities for an error handling path that encourages little awareness of the errors that can occur reeks of laziness to me. Laziness that I will, without a doubt, fall victim too without superhuman amounts of diligence on my part to avoid. Any problem that requires superhuman diligence just screams out for a robot to handle in my experience. Java, C#, Python and a myriad of other languages fail hard here. Go gets a little better culturally by focusing on checkers that are built into the compiler toolchain with a default to running culturally as well as having type a signature for return values clearly indicate the error. But the gold standard for error handling has to go to any language that has enumerated types. Rust, ML variants such as OCaml or Haskell as common examples.
