Ah, good catch. You are spot on. Names were just the first thing I thought of when trying to come up with an example. Thinking about it a bit more, there is a strong convention in functional languages to decompose lists into "first" and "rest" (regardless of what your language cares to name the functions that return these concepts). Especially in the case of infinite streams, "etc" seems to align with what you've described as the shifting usage in the term. I doubt CS is driving the shift in meaning. Just an interesting parallel I noticed.
