             Summary: Add collect(PartialFunction) methods to Scrunch APIs
                 Key: CRUNCH-422
                 URL: https://issues.apache.org/jira/browse/CRUNCH-422
             Project: Crunch
          Issue Type: Improvement
          Components: Scrunch
            Reporter: Josh Wills
            Assignee: Josh Wills


Scala's collection types support a collect(PartialFunction) method that acts like a filter followed by a map, and is implemented by Scala's case syntax, as in this blog post:

We should add some of this syntactic sugar to the Scrunch collection types.
