Arrow is a lambda, just like in Java.

I'm referring to the burden when changing languages. Swift and Rust use -> for the return type.

[int_19h]

And C++, C#, and JS use arrow for lambdas, so there's precedent for both.

My comment had nothing to do with lambdas. The point is that Kotlin uses fun and : instead of fn/func and ->, which is a needless and tedious break with other modern languages using Pascal-style function declaration.

Using val instead of let is similarly off-putting.
