Certainly, but lists are useful as interim data structure or for
initialising complex data structures.

Fine, someone shares my attitude towards the list sugar. Nevertheless, do
you mean with 'no sugar for lists' also no infix operator for list
construction? I would still like an operator of low precedence for list
construction for writing e.g. (1,'a"):(2,'b'):[].

Yes, this discussion is definitely beyond Haskell'.
