Well I expected decorators to be more flexible, i.e. to redefine test() by putting a wrapper around it and not to built a new decorator @test (!?!)
But I'm not too proficient with Python, and I'm misunderstanding the code.
(well, there must be a reason why I prefer Perl's syntactic flexibility. ;-)
I suppose def _(a) is a way to workaround the limitations of lamda?
Is the name _ special (magic) or is it just a convention?
