in reply to Object Oriented configuration values

To my taste application object and configuration object are quite distinct things so I would not mix them. Personally I'd make application object a facade to configuration object:

my $object = OurApp->new(...); print $object->config->base_directory, "\n";

Here $object->config returns config object. One advantage of this method is that fixes your problem with possible method and config variables name collisions.

It is also worth to mention that you are probably reinventing the wheel. AppConfig provides similar OO inteface to config files (i.e. config vars as methods)

[choroba]: if you turn off autocommit and run a prepared statement which fails, the transaction is automatically rolled back, at least in DBD::Pg
[erix]: at least, I'll know where to find the documentation :P
[choroba]: but if there's no prepared statement, there's no rollback
[choroba]: the rollback happens when deallocating the prepared statement in error state.
[choroba]: is this something that Pg enforces, or just a consequence of the Perl implementation?
[choroba]: also, does it make any sense? We run different statements generated from input structures, sometimes prepared statements are involved, sometimes not. We want the behaviour to be consistent.
