Call for Papers The Second ACM SIGPLAN Workshop on STATE in Programming Languages (SIPL) Jan 22, 1995 San Francisco Held in conjunction with POPL '95 Programming languages have been state-based since their inception. After a period of relative unpopularity, when research focused on declarative languages, interest in the treatment of state has been renewed. Research is increasingly devoted to finding a symbiotic relationship between the semantic foundations of declarative languages and the pragmatic handling of state in more conventional languages. This workshop brings together researchers from various areas, interested in the common issues of state manipulation in high-level programming languages. The first workshop in this series (SIPL '93) was held in Copenhagen in conjunction with FPCA '93. The proceedings are available as a Yale technical report YALEU/DCS/RR-968. A special issue of the Journal of Lisp and Symbolic Computation is being published as a follow-up to SIPL '93. Submissions are invited for the second workshop to be held in conjunction with POPL '95 in San Francisco. The workshop addresses the fundamental issues of expressing, manipulating, and reasoning about state in high-level programming languages. The range of topics includes operational and denotational models of state, assignment and references, semantics of object- oriented programming, calculi of state and methods to reason about state. Novel methods for expressing and controlling state- manipulation such as linear type systems, effect systems, and monads are also of interest. Formal presentations of results, research in progress, tutorials, and topical discussions are among the possible venues for interaction.
