Because the interpreter that mod_perl uses never ends, C<END { }> blocks won't
work properly. You should use C<PLP_END { };> instead. Note that this is a not
a built-in construct, so it needs proper termination with a semi-colon (as do
-<eval> and <do>).
+C<eval> and C<do>).
Under mod_perl, modules are loaded only once. A good modular design can improve
performance because of this, but you will have to B<reload> the modules
No warranty, no guarantees. Use PLP at your own risk, as I disclaim all
responsibility.
