Standard Evaluations

For each standard-pattern combination, we checked whether it is possible to realize the workflow pattern with the language. If a standard directly supports the pattern through one of its constructs, it is rated +. If the pattern is not directly supported, it is rated +/-. Any solution which results in spaghetti diagrams or coding, is considered as giving no direct support and is rated -. Note that a pattern is only supported directly if there is a feature provided by the language which supports the construct without resorting to any of solutions mentioned in the implementation part of the pattern.
