If you know the page's name, you can then pass its .pageorder, but then I'd rather pass a reference to the page object than the page's name - yet another way to avoid the macro. I'm really curious to know which one of these would be faster (here's the cases, in order of appearance):

- passing the page's name and using it as a macro
- passing the page's name and evaluating to an object using eval()
- passing the page's number and getting an object reference using ...pages[n]
- passing an object reference to the page

By "faster" I mean both the time needed to write/debug/maintain and the runtime benchmarks.
