I proposed this once upon a time: https://github.com/JuliaLang/julia/issues/1657; it wasn't popular. Please don't start commenting on that long-dead issue – keep the discussion here instead.

When you have a short one liner, the "end" part just does not feel right. It would be nice if the "end" could be left out for one liners. Even PHP allows one to skip the accolades in such cases. If there's some other way of achieving this I'd love to hear about it. I don't like the ternary operator in this situation cause it forces me to add the 3rd part as "nothing" or whatever. And doing "expr1 && expr2" only works when expr2 is "return" for instance, otherwise the compiler complains about using a non-boolean in a boolean context. vineri, 6 mai 2016, 20:37:49 UTC+2, Stefan Karpinski a scris: There is a long history of languages using this syntax, including Algol, Pascal, Ruby and Matlab.

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).
