How can I limit the available values of an enum for a given type

[pavel-savchenko-deel]

I'm following docs and using a string alias with enum constants to indicate the type on my struct (automatic via swago).

But, in my package, I also define additional constants that are special, such as const DefaultDifficulty = Easy (see type Difficulty string). Trouble is that automatic schema generator for enum picks them up twice, so in effect our enum array has easy twice, ["easy", "medium", "hard", "easy"].

I'm using swago v2 because I want it to generate OAS3. didn't test with v1 (I think it may have already had a fix for it, because I can't see this issue in some old v1 generated schema) Update: I can confirm that this issue doesn't happen in v1. And it appears in both OAS 2 and OAS 3.1 output. (with or without --v3.1 flag)

Does anyone know of a way to work around this (maybe a 'skip' option), or should this be reported as a bug?
