Thanks James and Laurent,

Actually this question was more to learn is it was possible. I
remember a post about keeping or not comment in the source code...

To be more precise, it's for log output of the inference system
(http://nars.seasidehosting.st/). In each step, there can be something
like 10 lines processes depending on entities are infered. The thing
is this log output chunks are mixed in the code in several places. I
could maybe use a better trigger mechanism like sending a signal with
the entity in question, but still, there will be this message sent (or
the test). I used stream and it seems ok (regarding performance), just
wanted to know if we could deactivate some portion of code as
everything seems possible here ;). I'll remind the subclass tip
though.

Cheers,

Cédrick
