What does it mean if there is a lambda with a nullable receiver? this can == null in the body of the lambda?
fun foo(block: String?.() -> Unit)
vs
fun foo(block: String.() -> Unit)
I noticed that with the second I cannot call .block() on a String? but the lambda body (for block param where foo is used) stays the same.

I see you found your answer already, but yes, this can be null in Kotlin, https://pl.kotl.in/H169XXRp7 for very simple example
