That's right, in both the regex and boost function cases, there is existing
practice (in that the libraries exist and have been used in the real world),
but that experience has also led the authors to revise their designs _in the
light of experience_. Those revisions haven't necessarily made it into
production code yet, but there is no point in discussing interfaces that are
about to change...
