Go panic isn't really usable as catch/rethrow because it can only be done at function scope. To make them useful for that pattern, you need a scoped `try { }` block where you can tell what part failed and continue from there. Either that, or you need lots and lots of tiny functions to form scopes around them.

You don't need "lots and lots" of tiny functions, most of the time it's totally fine to just let the exception propagate as is. When you do need to add information, you will have to use a function, yes, it's an unfortunate feature of golang. Same with defers, the only way to scope them is to wrap them in a function, it's stupid, but this is golang for you
