Second overload of IsNotNull crashes the kotlin compiler

[MartinHaeusler]

I've just tried upgrading from strikt 0.33 to strikt 0.34. It's a kotlin-JVM project with Kotlin 1.6.10.

In strikt 0.34, a second overload of the IsNotNull method was introduced:

/**
 * noop not null assertion on not nullable receiver
 */
@JvmName("isNotNullT?")
fun <T : Any> Builder<T>.isNotNull(): Builder<T> = this

The existence of this overload causes issues for the kotlin compiler. Code which worked fine on strikt 0.33 doesn't compile with 0.34 anymore because of this overload (Kotlin: [Internal Error] org.jetbrains.kotlin.util.KotlinFrontEndException: Exception while analyzing expression at ...)

In theory it should be possible to define a single isNotNull method that works on both nullable and non-nullable types, right? Or is the generic typebound on Builder<T> getting in the way?
