Raymond Hettinger <raymond.hettin...@gmail.com> added the comment:

+1 for a more informative repr (like we did with regex match objects).

There are a lot of parameters to subprocess.Popen().  RR is on the right track 
suggesting that only a small, useful subset of those be included:  args and the 
return code.  

We could add the *pid* argument as well, but may be no more useful or 
attractive than the current repr's object id.

The repr should be enclosed in angle brackets because it can't recreate the 
object.
