    resource function get<tab_nav> .<tab_nav>() returns json<tab_nav> {
        return {Hello: “World!”}<tab_nav>;

    resource function post test13(@http:Header string foo, @http:Payload json payload) returns {*http:Created json body}|{*http:Ok json body}|http:InternalServerError {
        
    }

    resource function get test15() returns <1>record {|*http:Created; RetPerson body;|} {
        RetPerson person = {age:1, name:"Joe"};
        return {
            mediaType: "application/person+json",
            headers: {
                "X-Server": "myServer"
            },
            body: person
        };
    }

}

• Completions snippet should be intelligent and tab navigations should provide at <tab_nav>
• At <1>. When returning a subtype of Status code response record, all the types of status code records should be suggested as http:Ok, http:NotFound.

Code Actions

• Code actions for the listeners to create a service out of them

Formatting

Module-HTTP

• Formatting should fix for the service and resources

General

• Code actions and the completion extensions can be shipped with each standard library with the available extension points (code action and completion)
