Increasingly, the software industry is making use of dynamic programming languages such as Python, Ruby, JavaScript, Lua, and Scheme. These languages offer many features which ease the development of evolvable complex applications: a rapid development cycle, introspection, language extensibility, parametric polymorphism, high level of abstraction, etc. Their main drawback in current implementations is their execution speed. The long term objective of the proposed research is to contribute to the efficient implementation of dynamic programming languages and evaluate how their performance compares to static languages in terms of execution speed, memory usage and implementation cost. Our goal is to develop implementation techniques which make them competitive in performance critical contexts. Four areas of research which extend our current work will be investigated:

软件行业越来越多地使用动态编程语言，如Python、Ruby、JavaScript、Lua和Scheme。这些语言提供了许多简化复杂应用程序开发的特性：快速开发周期、自省、语言可扩展性、参数多态性、高级抽象等。它们在当前实现中的主要缺点是它们的执行速度。该研究的长期目标是促进动态编程语言的有效实现，并评估其性能与静态语言在执行速度、内存使用和实现成本方面的比较。我们的目标是开发实现技术，使它们在性能关键环境中具有竞争力。将调查四个研究领域，以扩展我们目前的工作：
