Go isn't the right tool for ANY job
Just use const blocks, iota and enumer and be happy.

Does Go not have enums in the sense that I can use them as a type?
Define your type as an alias on int and values using iota as others have said, then autogenerate the rest of the functionality from other languages with https://github.com/dmarkham/enumer

Safer Enums in Go
We tried out struct-based enums like this for a while and they're definitely better than the vanilla version, but they still have the problem of "how do you iterate over all the values?" and "how do you create an enum value from a string?". We chanced upon https://github.com/dmarkham/enumer a few months ago and have been very happy so far.
Use enumer in combination with what some of this article.

> Use int-type enums with iota: no human-readable error values, no compile-time guard against illegal enum values
Create a new int type and use that for your enums. You have to try really hard to get a bad value in that case, and if it’s an unpunished type in a different package it’s even harder.
