I'm guessing the parent is just complaining that if you are reading code very fast (particularly if you're browsing repositories on your phone) it is hard to distinguish between "val" and "var."

Let alone type them wrong on a tired night.

Thankfully that would be a simple compile-time error. The message might even be readable.

If you type var and mean val - would there be any error?

(I'm sure that this is just something you need to get used to, I'm merely trying to point out that this could be a silent typo/mistake)

In many cases, you would get warnings when accessing a var that you don't get when accessing a val. Also, IntelliJ suggests converting to val if a var is never reassigned.

As others said, not a problem if you are using an IDE (and a specific one.)

Considering who authored the language, I am not surprised at all.

[Larrikin]

In actuality it will be extremely obvious in the IDE and the developer would not make this error.

[thomastjeffery]

if "val" is a constant, and you try to mutate it later, the compiler will tell you, "That ain't gonna happen."

It's even worse when your primary keyboard is Dvorak!
