Well, my C<use AutoLoader> would be _outside_ any of the loaded modules in the
mod_perl startup.pl script after all the modules necessary for proper execution of
_your_ mod_perl environment, are loaded.

That also makes sense, but wasn't my original idea.
I'd rather make this a class method, so:
AutoLoader->preload( @list_o_routines );
and have the module derive the module name from caller(). That would at least
simplify the call and it would reduce the risk of abuse.

I'm more interested in the modules that either work in a mod_perl environment and a
"normal" Perl environment. If a module is supposed to be used in mod_perl, it just
shouldn't use AutoLoader.
