Eh. Your construction is perhaps easier to understand if you've never used the language, and are trying to learn it just by reading arbitrary source code. But who writes code for such a person?
You might as well spell out:
int iterator;
for (iterator = ...
But everybody uses 'i', because it's faster and simpler, takes less time to read, and doesn't fill up your screen so that surrounding elements can be easily associated (e.g. a[i].do(x) vs myArray[iterator].doCoreFunction(element_x) <- yuck)
