Find if (x == null) throw IllegalArgumentException(...) patterns
Recipe ID
org.openrewrite.kotlin.functional.FindUseRequireForPrecondition$KtRecipeArtifact
io.moderne.recipe:recipes-kotlinKotlin's requireNotNull(x) { "…" } is the idiomatic precondition check: it throws IllegalArgumentException when x is null, smart-casts x to its non-nullable type after the call, and reads as the assertion it is. The if/throw form does the same thing without the smart-cast.
