Designing a programming language is a metaprogramming activity that bears certain similarities to programming in a regular language, with clarity and simplicity even more import... (展开全部) 作者简介 ······ H

For each construct, design issues are eXplored and eXamples from a variety of languages are presented. Both methods have merit. In order to accurately describe individual language concepts it is important to focus on the concepts and consider their impact on programming and the evolution of ...

1-* Summary OO programming involves three fundamental concepts: ADTs, inheritance, dynamic binding Major design issues: exclusivity of objects, subclasses and subtypes, type checking and polymorphism, single and multiple inheritance, dynamic binding, explicit and implicit de-allocation of objects, and ...

A closure is a subprogram and the referencing environment where it was defined – The referencing environment is needed if the subprogram can be called from any arbitrary place in the program – A static-scoped language that does not permit nested subprograms doesn’t need closures – Closures ...

Outstanding research that extends and/or applies programming-language concepts to advance the field of computing is welcome. Novel system designs, thorough empirical work, well-motivat...
