Even without an extra process, having to strip "-", assign an empty string to $extra, and then strip that empty string from the tail to come up with a single letter in $this, all are consuming cycles. Even though these wasted cycles are now much smaller, having an arm that specifically catches unbundled case and avoid doing anything extra makes the codeflow clear, I would think.
