A modern programming language that makes developers happier.

kotlinlang

What is the default for `languageVersion`? I'm using Kotlin 1.3.70, but when I try to pass a function that takes a default parameter to a type that expects the function to take no parameter I get the following error:

`The feature "function reference with default value as other type" is disabled`

And the quick fix is to set the module language version to 1.3
