Does this lead to a problem in your code? The sequence of cons cells is a list 
(fusion::list can be seen as just a convenient way of building a long cons cell sequence).
The cons sequence will behave exactly as a list. Maybe these functions should be
called as_random_access_sequence, as_bidirectional_sequence etc? Possibly
that would be less misleading?
