Report on the Algorithmic Language Scheme [6]

Programming languages should be designed not by piling feature on top of feature, but by removing the weaknesses and restrictions that make additional features appear necessary. Scheme demonstrates that a very small number of rules for forming expressions, with no restrictions on how they are composed, are enough to form a practical and efficient programming language that is flexible enough to support most of the major programming paradigms in use today. This book contains the three parts comprising 'R6RS', the sixth revision of a series of reports describing the programming language Scheme. The book is divided into parts: a description of the language itself, a description of the standard libraries and non-normative appendices. Early chapters introduce Scheme and later chapters act as a reference manual. This is an important report for programmers that work with or want to learn about the Scheme language.

Michael Sperber is an expert in creating high-level software models for complex problem domains. These models allow developers and users to represent domain-specific knowledge directly in the software, rather than forcing them to use awkward technical models.
