Scala example source code file (Dynamic.scala)

This example Scala source code file (Dynamic.scala) is included in my "Source Code Warehouse" project. The intent of this project is to help you more easily find Scala source code examples by using tags.

All credit for the original source code belongs to scala-lang.org; I'm just trying to make examples easier to find. (For my Scala work, see my Scala examples and tutorials.)

package scala

/** A marker trait that enables dynamic invocations. Instances `x` of this
 *  trait allow method invocations `x.meth(args)` for arbitrary method
 *  names `meth` and argument lists `args` as well as field accesses
 *  `x.field` for arbitrary field names `field`.
 *
 *  If a call is not natively supported by `x` (i.e. if type checking
 *  fails), it is rewritten according to the following rules:
 *
 *  {{{
 *  foo.method("blah")      ~~> foo.applyDynamic("method")("blah")
 *  foo.method(x = "blah")  ~~> foo.applyDynamicNamed("method")(("x", "blah"))
 *  foo.method(x = 1, 2)    ~~> foo.applyDynamicNamed("method")(("x", 1), ("", 2))
 *  foo.field           ~~> foo.selectDynamic("field")
 *  foo.varia = 10      ~~> foo.updateDynamic("varia")(10)
 *  foo.arr(10) = 13    ~~> foo.selectDynamic("arr").update(10, 13)
 *  foo.arr(10)         ~~> foo.applyDynamic("arr")(10)
 *  }}}
 *
 *  As of Scala 2.10, defining direct or indirect subclasses of this trait
 *  is only possible if the language feature `dynamics` is enabled.
