I said as much. ("This is an optimisation that should be transparent to you.") Misconceptions about the implementation details come up all the time. You've provided me with the perfect example in this paragraph. You believe it describes Perl when it doesn't. Where'd you get a list of preallocated structures from? Placing blocks of memory on a list for future use is how freeing a variable usually works. This is exactly what Perl doesn't do.
The quote line contradicts what seems to be a popular belief. The section describes what undef actually does (frees the buffers associated with the variable).
