Title: On the separation of queries from modifiers

Abstract:

The "Separate Query from Modifier" refactoring technique involves the
splitting of a function with side effects into two methods: a side-effect
free version of the function and a procedure dedicated for performing the
side effects. Being a refactoring, this technique involves the updating of
each invocation of the existing function with calls to the two new methods.

In the talk, a first attempt at automating this important refactoring is
presented, and the current status of an open-source slicing-based prototype
implementation for Java in Eclipse is reported.
