The one in Tango operates with a common type only; where perhaps you're 
combining the content of more than one collection (in Tango, you can 
populate a collection via an iterator, for example).

Combining mutliple lists of differing type is a somewhat different 
animal; if the lists are of differing lengths also, one might imagine 
all kinds of non-deterministic behaviour :)
