modperl_style.pod

Doug, I have a few questions regarding modperl_style.pod

=head2 Inheritance

=over 4

=item Avoid inherting from certain modules

Exporter
To void inherting B<AutoLoader::AUTOLOAD>
...
----------

Does it mean: Avoid using Exporter to void...?

also shouldn't:

*import = \&Exporter::import;
be:
local *import = \&Exporter::import;

--------

also can you please explain why:

=head2 Symbol tables

...
stay away from main::

Thanks!

One reason is because when using Registry, your script isn't in main::
anymore. This bit me once in porting CGIs to mod_perl.

that was a typo, s/void/avoid/

goodness no. file-scope local is useless.

same reason we have avoided it all these years. avoid namespace clashes.
