One issue is that "_" is still an actual identifier, with normal 
name collision rules. So that works only once. When you nest your 
loops, you'll end up having conflicts, and name your "i don't 
care variable" things such as "_", "__", "___", "_1", "_2" etc...

It actually happens quite often I find.
