The Scala Macro Paradise is available for 2.11 and 2.10. For 2.10, it says
you can already make use of quasiquotes in production versions of 2.10.x
Does that mean that 2.10 paradise is a subset of the 2.11 version? For instance, can I experiment with type macros, using Scala 2.10, or is that a feature for which I need to work with 2.11?
