In fact I'm wrong in any case. A naive recursive call seems to be just a hair faster than the goto, even when finding the median of a million-element list.
As you suggest, the fastest of all is to simply call the sub with an ampersand, but really the difference is very small. I wonder whether this is running into unshift's worst-case performance. Premature optimization and all that…
