Quote or be quoted

In Scala 2.11 we introduced quasiquotes, a rich domain-specific api for tree manipulation. Despite advanced functionality and deep integration into the language, the api itself is just a library that relies on existing language features: string interpolation, macros, type classes etc. This talk will walk through implementation of custom quotations for a tiny language embedded within Scala and introduce you to core concepts used in quasiquotes: splicing, cardinality, lifting/unlifting and show how all of this makes your life easier. Author: Denys Shabalin Denys is the author of Scala 2.11's quasiquotes, a project aimed at making AST manipulation a pleasure. He is also an active contributor to scala/scala repository, hacking on compiler internals, reflection API and macros. At the moment he works as intern at Typesafe researching ways to introduce referential transparency and hygiene concepts to Scala compiler and macro system.
