Language request: Ballerina

Language

Ballerina is an open-source programming language for the cloud that makes it easier to use, combine, and create network services.

A simple REST API can be written in Ballerina as follows.

import ballerina/http;

listener http:Listener httpListener = new (8080);

service / on httpListener {
    resource function get greeting() returns string { 
        return "Hello, World!"; 
    }

    resource function get greeting/[string name]() returns string { 
        return "Hello " + name; 
    }
}
