Thank You for pointing out at Moose::Manual::Construction, which is not about Moose construction, but constructing objects in Moose. I should not have ignored that :-(

In short, the problem is I read Log4Perl initialization from a file, for two logfiles, one technical log and one specialized log changing over the time. To create the second one on-the-fly I use the patterns from the config to create a layout class and an appender, which is later used to generate the second logfile. The reason for this is that File-Appenders create the files on construction, but I do not have a filename at that time. So I gather and create all things I need at the beginning to use them when I first have a logfilename. Later I can use file_switch() on the appender but that is Log4Perl. Expensive? I really do not know. My philosophy/religion is that constant things should be initialized at the beginning, when they are used more than once.

I think You are right, I might solve this by reordering my builders and revisting the examples.

Thank You again for Your patience
