in reply to An Apology for Puncish

The concept of the default variables is not without its linguistic roots.
Consider this sentence "Jack stood when Jill entered," and "he did it because she was tired".
This makes perfect sense, to anyone with fair reading skills. If you just started on reading, and are not familiar with the idea of context; or, if your overall reading comprehension skills aren't that good, you might need to explicitly read it as "Jack stood up when Jill entered, Jack stood up because Jill looked tired when she entered."

Now, if the second part of the sentence appeared 3 or 4 paragraphs later, there would be a need to use the explicit version of it, rather than the pronouns one.
In this sense, if the nature of the special variable is important to the understanding of the code, use English is a good practice. In the same way that naming your iteration variable is, at times, a good practice. Otherwise, feel free to be punc'd.
