listing all job variables

System

I just had a need to list all of the job variables in a CGI task (there's an incredibly long story behind this that no one really wants to know about), and discovered much to my surpise and chagrin that WFworkflow.pm does not have a method for getting the list of variables. No problem, I thought, I'll just call iwjobvariables directly. My surpise was greatly increased when I discovered that it also lacks any ability to do this.

Has anyone else out there ever had this need, and if so, how did you solve it?
