The previous API had ``` fun fixture(factory: () -...

The previous API had

fun fixture(factory: () -> F)
fun modifyFixture(block: F.() -> Unit)
fun replaceFixture(transform: F.() -> F)
fun deriveFixture(transform: PF.() -> F)

rather than just (as now)

fun fixture(factory: ParentF.() -> F)
fun modifyFixture(operation: F.() -> Unit) = before(operation)

I think that if I return to the previous one, I can support deferring the fixture setting until a context actually needs it (has tests, or befores or afters)
