Modernize Kotlin functional / Result ergonomics
Recipe ID
org.openrewrite.kotlin.functional.Functional$KtRecipeArtifact
io.moderne.recipe:recipes-kotlinSearch-only recipes that surface kotlin.Result / runCatching { } smells and try/catch shapes that map cleanly to Kotlin idioms (.fold(...), .getOrNull(), .getOrDefault(...), ?:, ?.let { }, requireNotNull, checkNotNull). Most of the actual rewrites involve moving statements between try-body / catch-body / Result-chain shapes, which the declarative rewrite { } to { } DSL doesn't model yet — so each match is a SearchResult for human review.
