/** 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.
