   typedef is very much used in C.   
      
   Type declarations are part of the Pascal way.   
      
   But I don't think it is the same in OO languages.   
      
   I have never heard a Java developer ask for it.   
      
   C# has the functionality (in using directive). But I   
   have never used it myself and I don't think I have   
   ever seen code using it (note: I am talking about   
   using for type alias only - using for namespace alias is   
   used occasionally).   
      
   Kotlin also has it and even though it is used then   
   I would call it rare.   
      
   I cannot demo C# on VMS< but Kotlin runs on VMS, so:   
      
   $ type ta.kt   
   typealias OneToMany = Map>   
      
   fun dump(m: OneToMany, rt: String) {   
        println("$rt:")   
        for(lang in m[rt].orEmpty()) {   
            println("  $lang")   
        }   
   }   
      
   fun main() {   
        val m: OneToMany = mapOf(Pair("JVM", listOf("Java",   
   "Kotlin", "Scala", "Groovy")),   
                                         Pair("CLR", listOf("C#", "VB.NET",   
   "F#")))   
        dump(m, "JVM")   
        dump(m, "CLR")   
   }   
   $ kotlinc """ta.kt"""   
   $ java -cp .:/disk0/net/kotlin/kotlinc/lib/* "TaKt"   
   JVM:   
      Java   
      Kotlin   
      Scala   
      Groovy   
   CLR:   
      C#   
      VB.NET
