Thanks for the explanation !
BTW, what happens if I do "import os" and then I do a "os=Thing()" and I
do "print os.name", assuming that my Thing instance has a name="Hello"
property ?

I guess it will print "Hello" ....but what is the scope of name
resolution, something like block->function->class->module ?

Cheers,
Seb.
