returned = cmd.issue

returned would hold an object of class Stderr (or equiv) if there's an 
error output from the command, an object of class Stdout (or equiv) if 
there's anything from the command's stdout, or it would hold nil if 
there's none of those.
The pseudo code was merely for demonstration, so I chose a way I found 
descriptive.
