I don't much like this syntax, because

  str | radix(10)

isn't meaningful by itself.

Also, for what it's worth, when this discussion moved from simple
to_string/to_int type functionality into the realm of a "generalized
conversion framework," I mostly lost interest.

I haven't been watching closely, so I could be wrong, it seems like a
classic premature generalization... the same one, in fact, that makes
lexical_cast unsuitable for many people's purposes. Generic components
can only properly arise from a survey of many specific, non-generic
components. Have we done that for this "generalized conversion utility"
or is the interface being designed speculatively to allow for something
that maybe nobody wants or needs? We have to_string and to_int as
non-generic exemplars. What else has been looked at?
