Rain: A New Concurrent Process-Oriented Programming Language

摘要

This paper details the design of a new concurrent process-oriented programming language, Rain. The language borrows heavily from occam-π and C++ to create a new language based on process-oriented programming, marrying channel-based communication, a clear division between statement and expression, and elements of functional programming. An expressive yet simple type system, coupled with templates, underpins the language.rnModern features such as Unicode support and 64-bit integers are included from the outset, and new ideas involving permissions and coding standards are also proposed. The language targets a new virtual machine, which is detailed in a companion paper along with benchmarks of its performance.
