Yes, well, I wouldn't do that, and especially wouldn't use each in two nested loops ...

I'd at least do this:
 [ [1,2], [3,4] ].each {|eachArray| eachArray.each {|eachInteger| p eachInteger}}

and more likely:

 [ [1,2], [3,4] ].each do|eachArray| 
   eachArray.each do |eachInteger| 
     p eachInteger
   end

Smalltalkers use 'each' for that variable, so that's why we do it. If the variable's type
isn't obvious we might call it 'eachFilename" or the like.

I don't read enough Ruby code to know if there's a standard thing naming convention for
the iteration variable. Is there?

I'm giving the best advice I have. You get to decide whether it's true for you.
