Program Metamorphosisare limited in three ways: (i) atomicity forces transformations to be complex and opaque, (ii) the behaviour preservation requirement disallows deliberate behaviour evolution, and (iii) atomicity limits code reuse opportunities for refactoring implementers..We present ‘program metamorphosis’, a nove

GUILT

From Public to Private to Absent: Refactoring , Programs under Constrained Accessibilitye tools provide hints that referenced elements may become inaccessible due to the intended restructuring, none we have tested prevent changes that alter the meaning of a program, and none take steps that counteract such alterations. To address these problems, we formalize accessibility in . as a set

Implicit Dynamic Frames: Combining Dynamic Frames and Separation Logicf writing frame annotations. From the precondition, one can then infer an upper bound on the set of locations writable or readable by the corresponding method. We implemented our approach in a tool, and used it to automatically verify several challenging programs, including subject-observer, iterator and linked list.

Modular Visitor Components previous work exploring the connection between type-theoretic encodings of datatypes and visitors, we propose two solutions for this problem in Scala using .. These components can be grouped into . that can be easily composed in a . style to obtain customized datatypes and operations.

Debugging Method Namesva defines an implicit convention for pairing names and implementations. We exploit this to extract rules for method names, which are used to identify “naming bugs” in well-known Java applications. We also present an approach for automatic suggestion of more suitable names in the presence of mismatch between name and implementation.

,Ballenfu?, Hohlfu?, Hackenfu?,n adding type-level functions to Haskell, as I will briefly describe..I will explain what type classes are, how they differ from the classes of mainstream object oriented languages, why I think they are so cool, and what the hot topics are. I’ll give plenty of examples, so you don’t need to already know Haskell.
