Dijkstra argued that GOTO statements should be abolished because they lead to unstructured control flow and complicate the analysis and verification of programs. In 1974, Don Knuth presented an alternative viewpoint in Structured Programming with go to Statements. He showed that for some common programming tasks, GOTOs are the best language construct to use. This was more than 30 years ago. Today (and looking into the future) the programming landscape is changing because of the new software crisis. How would structured programming help programmers more rapidly express their parallel computation? What are some of the tradeoffs they might
