Many thanks to all for the replies

Could the interval for element x of List xList overlap with more than
one element of another list? It does not matter too much, but is
something you did not clarify. In general, how may the intervals for
all the lists overlap? (The answer may be too complex, in which case
you can just ignore me).
Yes, unlimited overlap is possible. e.g. Infinite interval in one list, and
infinitely many small intervals in another list.
I would start by merging, perhaps in stages, into an intermediate list
with elements of its own "data FooIntermediate = A _ [_]| B _ [(_,_)] |
C _ _ _ | ..." types.
Yes, I'll probably use this suggestion, maybe with records to make partial
update easier.
If you need to change the semantics of merging the streams then it may
help when you refactor that the types of events are now types of
constructors and the compiler is checking your code.
Originally I had thought that I could treat the merge symetrically, but I
now think this is not the case. Still I am not sure if I will use different
types for different types of merge.
Rene.
