Shouldn't

public operator fun <T> Iterable<T>.minus(element: T): List<T>

be defined with element as nullable?

public operator fun <T> Iterable<T>.minus(element: T?): List<T>

I.e. if you call listOf<String>(...) - null as String? it would just return the same List<String> and not List<String?> as it currently does.

This has to investigated, whether it's possible to add something like this: https://github.com/JetBrains/kotlin/blob/1.1.0/libraries/stdlib/src/kotlin/collections/MutableCollections.kt#L15
so that type of element to be removed could be any direct supertype of element type of the collection.
