Does anyone else use this little idiom?

Sometimes, but not often.

If I'm writing a use-once-then-throw-away script, it's too much trouble 
to press the Shift key to get an underscore *wink*, so I tend to just use 
i or x for the loop variable.

If I'm writing something I intend to keep, but don't care too much about, 
I'll use _, i or x about equal numbers of times, depending on whim.

If I was writing something important I expected others to read, I'd use 
dummy.

I wouldn't go so far as to say "Don't use that idiom!", but it's not 
something I use often.
