alt Hacker NewsYeah, this is the single biggest reason I avoid go - I just don't want to clutter my "happy path" logic. It makes things harder to reason about.
"Errors are values", sure. Numbers are values and Lists are values. I use them differently, though.
I wonder if there could be "stupid" preprocessing step where I could unclutter go code, where you'd make a new token like "?=", that got replaced before compile time. For instance, "x ?= function.call();" would expand to "x, err := function.call(); if (err != nil) return err;"
There's no happy path in programming. Errors are just some of the many states in the code and the transition to them doesn't disappear magically because you chose to not specify them. Actually returning an error is just a choice, you can chose to handle the situation, maybe log the error and go on your merry way. Or you panic() and cancel the whole call stack back to a recover(). I like Go because it forces you to be explicit.
