A prime concern in the design of any general purpose programming language should be the ease and safety of working with natural numbers, particularly in conjunction with discrete data structures. This theme of commitment to the naturals as the basic numeric data type is explored in the context of a lazy functional language. Non-Title

In this paper we argue that it is possible to couple the advantages of programming with the well-known abstraction of RPC with asynchronous programming models adequate for wide-area programming environments such as grids. We discuss how some programming language features can help create different programming abstractions over a basic asynchronous invocation primitive. The paper also discusses h...

PLT Scheme (DrScheme and MzScheme) supports COM components with two pieces of software. The rst piece is MzCOM, a COM class that makes a Scheme evaluator available to COM clients. With MzCOM, programmers can embed Scheme code in programs written in mainstream languages such as C++ or Visual BASIC. Some applications can also load MzCOM. The other piece of component-support software is MysterX, w...
