Compossible: Extensible records and type-indexed maps. Compossible is a new, easy to use library implementing extensible records and type-indexed maps (TMaps) based on intersection types. Extensible records are a more modular alternative to case classes. Type-indexed maps are type-safe maps without the need for key names. Example usage: src/test/scala/RecordTest.scala src/test/scala/TMapTest.scala Sbt setup: resolvers += "Sonatype OSS Snapshots" at "https://oss.sonatype.org/content/repositories/snapshots" libraryDependencies += "org.cvogt" %% "compossible" % "0.2"
