Thanks Gabriel. This sounds very nice for my purpose.
I have some doubts however. How do I "transform" a list into
MyList? Is this the best way?

class MyList(list):
	def __init__(self,l=None):
		if l != None:
			self=copy(l) (or self.extend(l) - this does not need copy module)

Then I can do something like xl=MyList([ ... ])

I read the description of __new__ but I didn't fully understand it and
didn't find any examples on how it is used.
Is it usable in this context? How?

Thanks
Paulo
