%0 Journal Article %T Syntax and Semantics of Babel-17 %A Steven Obua %J Computer Science %D 2010 %I arXiv %X We present Babel-17, the first programming language for purely functional structured programming (PFSP). Earlier work illustrated PFSP in the framework of a toy research language. Babel-17 takes this earlier work to a new level by showing how PFSP can be combined with pattern matching, object oriented programming, and features like concurrency, lazy evaluation, memoization and support for lenses. %U http://arxiv.org/abs/1012.2294v4
