Thanks :)

I'll include it in our standard test*sh scripts :)

Yes, but it will warn us about all properties in fact, taht why it
will be hard to see real errors in it.

I do not really like docstrings. In fact, it's the separation between
the function prototype and the real code that annoy me. I like to see
the comments before the function, so I can see in the prototype and
code in quite the same lines. But maybe I didn't look enough to others
Python code for this. I'll try and see if it's so annoying that it was
for me :)

Oh yes, it's not a problem for him. It just need some more code to put
random ports and catch some things like it, but such part of code need
to be fully tested :)
