Wafe provides a flexible and easy to use interface to the X Toolkit (Xt) and the Athena widget set (Xaw) using the embeddable command language Tcl [1]. It allows access to Xt’s...
We develop a calculus for lazy functional programming based on recursion operators associated with data type de nitions. For these operators we derive various algebraic laws that ...
We report on an extension of Haskell with open type-level functions and equality constraints that unifies earlier work on GADTs, functional dependencies, and associated types. The...

We describe extensions to the Excel spreadsheet that integrate userdefined functions into the spreadsheet grid, rather than treating them as a "bolt-on". Our first objec...

Five implementations of di erent lazy functional languages are compared using a common benchmark of a dozen medium size programs. The benchmarking procedure has been designed such...
