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!
