Some JSON schemas cannot be expressed using Wing's json structs

[eladb]

I tried this:

Wing's json structs (structs that can be serialized into JSON) are designed to be able to express cloud data shapes. As such, they are closely related to JSON Schemas.

Currently, Wing's type system doesn't have the ability to express everything that JSON schemas can express.

For example, the oneOf and anyOf annotations can be used in JSON schemas to denote a union of possible types for a field, and this is currently not supported by the Wing type-system.

Consider the following JSON schema:

{
  "oneOf": [
    {
      "type": "string",
      "maxLength": 10
    },
    {
      "type": "integer",
      "minimum": 0
    }
  ]
}

I expected this:

I expect to be able to model this in Winglang somehow.

Instead, this happened:

I don't have a way to model this.

Is there a workaround?

We can start by using Json to model these schemas without strong typing.

If that's suitable for my use case, I could just choose the first schema from the anyOf or oneOf arrays and use that, but this doesn't really address the underlying issue.
