Personally, I think that i is just fine in many cases where it's quite clear what 
you're doing. e.g. the standard for loop:

for(size_t i = 0; i < a.length; ++i)
  //whatever we do with a[i]...

foreach does reduce how often that sort of thing is necessary though. However, 
once you get beyond i, and maybe j, it just gets confusing (not to mention the 
fact that i and j look a fair bit alike). So, personally, I avoid going beyond 
i, and I don't use i unless it's quite clear what I'm doing. Other than that, I 
find clearly named variables make the code much easier to read and understand - 
especially if someone else wrote the code, or you haven't read it in a while.
