But it involves repeating C<@rray> -- which for more complex expressions
(results from function calls, delving deep into very nested data
structures, whatever) could be tedious. Repetition is certainly poor
style and makes the code more prone to errors being introduced.
Also, it relies on the contents of C<@rray> not being cleared inside the
loop.
