It would be of a great value if the jobDSL Playground Engine, which links now to http://job-dsl.herokuapp.com/ can run internally Dynamic-DSL style as presented in https://github.com/jenkinsci/job-dsl-plugin/blob/master/docs/Dynamic-DSL.md 

To simplify if the Jenkins installation is available at http://localhost:8080 the DSL API viewer will be available at http://localhost:8080/plugin/job-dsl/api-viewer/index.html and the Playground can be available at http://localhost:8080/plugin/job-dsl/api-viewer/index.html or a configurable internal location so you can take advantage of Dynamic-DSL
