I feel proponents of any programming language put a lot of spin around what isolated aspects it is good for, but fail to illustrate what a programmer in even one target domain gains from using it.
Are there programming language implementations unlike what is described above, that you feel back up their marketing?
There are many easy-to-learn languages, and others actually have useful software development ideas (immutable by default, for example). I understand if expectations are lower, though, from the language talk, and if any language with the required libraries is fine.
