Enhancing Show-and-Tell with a polymorphic type system and higher-order functions

Abstract

Enhancements to a visual dataflow language called Show-and-Tell (STL) are described. These enhancements enrich STL by a polymorphic-type system similar to the one used in ML, and they introduce user-definable higher-order functions. A short overview of STL is given, and the concept of higher-order functions is discussed.<>
