The following should be allowed and tested: ``` global { var1=$var2 var2=42 } ```

When a workflow has been run with non-comparable versions, a warning should be generated. Both before execution (so that the user can invalidate old versions if desired) and when reports...

It might be useful to allow a maximum number of instances of a single resource-hogging task to run at a single time. Example: Task 1 involves a large amount of...
