I sympatjise but to be honest  I never use the backtick trick except at 
the >>> prompt as a quick and dirty hack. It ranks alongside the _ variable 
in my book as an interactive utility but it's too easy to miss or misread to use 
in real code.

But even popen is easier, I agree, and I am still weaning myself away from 
popen to Popen... But I can see the reasoning behind the move.

Of course if you do a lot of that you could always define a function 
that supplies default values for everything but the command.
