If we have a data structure which we will need to output to a file and we
don't know in advance which or how many file formats we will need to
support, what's the best design pattern to implement the routines to dump
the data to a file?
Thanks in advance,

This is a classic full multiple dispatch case: Write/Read defined on two

independent type hierarchies: Medium and Persistent. A similar case is Draw
over Surface and Shape. Visitor pattern is usually suggested as a poor
man's solution when the language offers no multiple dispatch.
