Do we really need so many new programming languages? There is no doubt that the choices currently being made by developers are quite rich. command-type languages, functional languages, object-oriented languages, dynamic languages, compiled language interpretive languages, and scripting languages and so on seem to have completely covered all the tasks we might face, and few professionals today have been able to understand all the languages. However, new languages are still springing up at an alarming rate. Some are designed by students or enthusiasts in the form of personal projects, others from large it vendors. Not even ...
