The benefit would be it being optional. You only need it while learning the language, whereas once you're familiar with the notation the terseness becomes a feature. Of course once you've come up with clear names for each symbol you could do the opposite, let the IDE turn `plus reduce range 100` into `+/!100`. But as long as IDEs are still glorified text editors and devs care about the representation that gets stored on disk I would argue making the terse notation the default is the right choice.
