and the `preprocess` function is the one that ikiwiki will call to expand
Feel free to try it out with a simple page like this:
- \[[fib ]], \[[fib ]], \[[fib ]], \[[fib ]], \[[fib ]]
+ [[fib ]], [[fib ]], [[fib ]], [[fib ]], [[fib ]]
Looks like it works ok, doesn't it? That creates a page that lists:
Obviously, using a global `$last` veriable was a bad idea. It would
