It would seem to me that having the analysis routine do the I/O itself
is more coupling than designing it to be datasource-agnostic!

I'd expect it to be much neater to thread the data through the various
functions comprising the analysing functions, perhaps monadically, as a
part of its design; and then to feed the data in at a single entry
point. Thus the entire analysis is pure.
