Description

I've got some query parameters that are arrays of strings, and have default values listed:

         {
            "description": "Data to include in response",
            "explode": false,
            "in": "query",
            "name": "include",
            "schema": {
              "default": [
                "userstats"
              ],
              "description": "Data to include in response",
              "items": {
                "enum": [
                  "word",
                  "userstats"
                ],
                "type": "string"
              },
              "type": [
                "array",
                "null"
              ]
            }
          }

        {
            "description": "Data to include in response.  'analysis' requires a userid to be specified.",
            "explode": false,
            "in": "query",
            "name": "include",
            "schema": {
              "default": [
                "title",
                "text"
              ],
              "description": "Data to include in response.  'analysis' requires a userid to be specified.",
              "items": {
                "enum": [
                  "cguid",
                  "title",
                  "text",
                  "analysis"
                ],
                "type": "string"
              },
              "type": [
                "array",
                "null"
              ]
            }
          },

I would think "default values" means "values that the server will use if nothing is provided"; but the generator seems to try to fill in these values. Unfortunately it generates syntactically invalid Go code:

	if r.include != nil {
		parameterAddToHeaderOrQuery(localVarQueryParams, "include", r.include, "form", "csv")
	} else {
		var defaultValue []string = [userstats] // BUG: Should be {"userstats"}
		r.include = &defaultValue
	}

	if r.include != nil {
		parameterAddToHeaderOrQuery(localVarQueryParams, "include", r.include, "form", "csv")
	} else {
		var defaultValue []string = ["title","text"] // BUG: Should be {"title","text"}
		r.include = &defaultValue
	}
