It is quite superficial. Code being easy to read is much more important than code being easy to write. I'm not saying it's a bad idea to have both, but look at Java or C# that are a pain to write without a very smart IDE (just because of the amount of boilerplate). Even they have been saved by tooling.

Also, modern popular languages tend to use arrows (Java, C#, ES6). Not to say that popularity matters, but people are used to it nowadays.
