The best way to use autoload is with the auto_prepend_file configuration
directive. By adding the __autoload() function to a file that is
automatically prepended, you don't even have to think about it in your
scripts.

This kind of flexibility is nice -- you can have different prepend files
for different sites or different areas of the same site -- so that you
only have the funcationality accessible that you need right there. You
can also define your own naming schema -- which, admittedly is a dubious
advantage, but an advantage nonetheless.
