Tuples don't have list methods, therefore any code which seems to require a 
tuple with list methods should make you stop and consider whether your 
design is wrong. Your example made me consider your design was wrong. If 
tuples did have list methods you would have gone ahead with a poor design.

That is why I said that, to me, it is an argument against giving tuples the 
additional methods. It is a fairly weak argument though, so if you do have 
some other use case you could easily prove me wrong.
