What is rubbish about that - except from the obvious cleansing of input 
variables that has to take place? Python has a whole module dedicated to 
that rubbish, called subprocess.

While I certainly prefer to use Python wherever I can, that does not 
mean that there aren't cases where legacy systems or other constraints 
make this impossible. If I have e.g. a type3-based website - "how on 
earth" should I replace that with Python (without wasting a lot of time)?
