uu for programming languages
Ulisses Ferreira · ACM SIGPLAN Notices · 2000
The Internet has motivated new programming language features and, in this article, we consider that programming for such a global environment requires the ability to deal with what is unknown because connections often fail or delay and programs should be robust. Thus, we concentrate on this particular issue.In this article we present uu , a value that can represent lack of information in programming languages. A thesis is that this value is a good feature towards the unification of some programming paradigms. Thus, in this article, we explore constructs as consequences of uu in such languages together with examples where this value helps in programming, and we explain the relationship between uu and another programming paradigm. The implementation of uu is also briefly discussed.
