I realize TFA is trying for object code, but for source code, QuickBASIC (and its successors) isn't bad: ? "hello, world!" PILOT eliminates the quotes: T:hello, world! Of course a typical REPL (Python, JavaScript, Lisp, etc.) will print out something similar (but often quoted) if you just type the quoted string. And I'm sure there is already some language (call it HELLO) which simply prints "hello, world!" for an empty program.
