Listed below are all of the tasks on Rosetta Code which have been solved using Wrapl.

Wrapl is a dynamic programming language designed for various programming tasks including rapid prototyping, scripts andGUI application development.

The key features in Wrapl include:

• Object-oriented: Every value in Wrapl is an object with a type which is known atrun time. The types form a hierarchy withmultiple inheritance.
• Multiple-dispatch: Method dispatch in Wrapl depends on the types and values of all of their arguments.
• Pass-by-reference: Wrapl allows variables to be passed by reference to other functions.
• Functionalclosures: Functions in Wrapl are first-class objects which may passed to other functions or stored in variables. Functions can both read and write variables declared in surrounding scopes.
• Goal-directed: Every expression in Wrapl can produce 0, 1, or more values. An expression which can produce more than 1 value may be resumed to produce its next value.
