`doto` for Scala

Clojure offers a macro called doto that takes its argument and a list of functions and essentially calls each function, prepending the (evaluated) argument:

(doto (new java.util.HashMap) (.put "a" 1) (.put "b" 2))
-> {a=1, b=2}

Is there some way to implement something similar in Scala? I envision something with the following form:

val something =
  doto(Something.getInstance) {
    x()
    y()
    z()
  }

which will be equivalent to

val something = Something.getInstance
something.x()
something.y()
something.z()

Might it be possible using scala.util.DynamicVariables?

Note that with factory methods, like Something.getInstance, it is not possible to use the common Scala pattern

val something =
  new Something {
    x()
    y()
    z()
  }
