ACM Transactions on Programming Languages and Systems (TOPLAS) is the premier journal for reporting recent research advances in the areas of programming languages, and systems to assist the task of programming.The scope of TOPLAS includes, but is not limited to, the following subjects:language design for sequential and parallel programmingprogramming language implementationprogramming language semanticscompilers and interpretersruntime systems for program executionstorage allocation and garbage collectionlanguages and methods for writing program specificationslanguages and methods for secure and reliable programstesting and verification of programsPapers can be either theoretical or experimental in style, but in either case, they must contain innovative and novel content that advances the state of the art of programming languages and systems. We also invite strictly experimental papers that compare existing approaches, tutorial, and survey papers.
