Is there any reasoning behind it? It seems to me like a weird choice since
you have to type three letters, which is the complete opposite of the goal
of this language - being very productive (a lot work done with little code).
On top of that, brain has to read the word every time your eyes look at it
so you spend more time also reading the code - tho this should be easy to
omit, by highlighting this keyword by other color than other keywords (the
current purple color in ATOM just drives me crazy, since it is one of the
most violent colors, so my eyes always try to read that useless piece of
information first, instead of the important code).
