That sounds a bit dismissive. Who would do that complaining? I would 
like to be able to do this for scripts I write for myself. If these 
scripts have something to tell me, they should make sure I get to see 
that. If they don't, the console can disappear (if started from 
explorer). I can do this with "input('Press enter when done')" easily; 
however, if I start the script from a console window I get to press 
enter too, needlessly.

I specifically asked for the opposite of consistency.
