Answers http://stackoverflow.com/questions/10373318/mixing-in-a-trait-dynamically.

Compile as follows:
scalac Common_1.scala Macros_2.scala
scalac Common_1.scala Test_3.scala -cp <path to the result of the previous compilation>

Tested in 2.10.0-M3, will most likely not compile by the time 2.10.0 final is released, because we're actively rehashing the API. 
However the principles will remain the same in the final release, so the concept itself is okay.
upd. Code updated for 2.10.0-M7.
