[Boost-users] Question about Any usage

I have a question about the use of Any, especially when used in a larger
facility such as program_options.  There doesn't seem to be a (easy) way to
post-process the results of a facility that has generically stuffed a bunch
of values into a list of Any's.  For example, if I wanted to a program to
spit out all of its options to standard out, there doesn't seem to be any
hooks to extract an Any value in a generic way (e.g., as a string).
Granted, I could derive a class and add methods to do so, but that doesn't
work when Any is already embedded in the program_options implementation.

I certainly could be missing something here.  I haven't used Any or
program_options yet, and trying to understand all of the possibilities from
the spec-like doc is hard.  How do the rest of you do such things?
