Do you mean the list, or do you mean the list/the tuple/the dict/the 
generator/the file and anything else which just happens to be an iterable 
sequence of strings?

join is a factory method for creating a string from a separator string and 
a sequence of strings, any sequence of strings. It doesn't make sense to 
either limit it to specific sequence types, or to require it as part of the 
iterator protocol.

Having it as a function would make sense, but if it is going to be a method 
then it should be a method on the string types not on the sequence types.
