I meant that it is used in Session. The object layer doesn't even need
to know POE, although it might be easier.

yes. but you would kill oneliners somehow, if tool support is needed.
the object layer should make it easier to write these.

i don't really know what's better. explicit is certainly easier. usually
i'm a "do it right" type of person, but currently a starting point or
a good amount of code would make me feel better ... :/ especially with
all the p5ee activity or at least lots of talk about it ...
