Tuples vs Lists: Semantic difference (was: Extract String From Enclosing Tuple)

George Sakkis, I agree with the things you say.
Sometimes you may have a sequence of uniform data with unknown len (so
its index doesn't have semantic meaning). You may want to use it as
dict key, so you probably use a tuple meant as just an immutable list.
I don't know Ruby, but I think it allows such purposes with a freezing
function.
