I'm very new to Go - apologies in advance if I'm missing something: I find it frustrating that there's no way to create a map that does *not* automatically return a zero value for undefined key access by default.
I love the fact that Go doesn't return "nil" for this use case (I love Ruby, but I don't think they got that quite right), but returning a default value is worse! It would make so much more sense if it would just panic when accessing an undefined key. I'm not a Python guy, but I think this is something Python got right. Creating a map that returns some default value when you access an undefined key should be a special kind of map, or a special argument to initializing the map (which Ruby does allow). In Go, is there even any way to create a map that panics when you access an undefined key? -Joe -- *Connect with us here:* LinkedIn <https://www.linkedin.com/company/smarter-sorting/>, Facebook <https://www.facebook.com/smartersorting>, Instagram <https://www.instagram.com/smartersorting/>, Twitter <https://twitter.com/SmarterSorting>, BuiltInAustin <https://www.builtinaustin.com/company/smarter-sorting> <https://www.smartersorting.com/> <https://www.builtinaustin.com/2019/02/05/50-austin-startups-watch-2019?utm_source=PE&utm_medium=organic_social&utm_campaign=50_STW_PE&utm_term=article&utm_content=austin> -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
