As a follow-on question, why would this be implemented only now? From the very beginning, capturing the stdout of an external command involved forking a subshell, and soon (assuming funsubs remain when 5.3 is released) it won't have to. It feels like something changed to make this feasible when it hadn't been before. Zack
