Echoing what RonW said, I think that particular reasoning is from a pre-high-level language mindset where there aren’t all that many ways to write a piece of code and they will often collapse to a similar number of ops when compiled. There are so many ways to write a line or block or package of Perl that diddling is harder to define… but you should know it when you see it. Apologies to the ghost of Justice Stewart.
