This is one thing I'm certain of after 40 years of programming: successful programs will need to be read more often than they are written. Language features that make programs cool or fun or "easy" to write are generally counter-productive to readability. Even things like this that are meant to make a program "expressive" are in fact just gimmicks if they are unique to one program. Features that make a language expressive in a consistent way are very valuable though. Python is a good example of this, even people who don't know anything about Python can generally read a Python program.
