Thanks, but I suspect that it was my bad description of the issue that made
understanding the issue more problematic.

Anyway it's good we now understand each other, and even better that we agree

As an aside, has anyone written the code necessary to convert a parser, such
as e.g.  attoparsec, into an enumerator-iteratee[1]?
