I have a situation where I'd like to experiment with this library, but I do not
have time to start it yet. Perhaps my mentioning it is half-way valuable,
though, so here goes :)

When I saw the announcement, I immediately thought about using the library to
store and access Unicode text. Specifically, I am imagining that it might allow
me to create a string type that acts as a randomly accessible sequence of
glyphs. Each glyph would be a flyweight<>.

Most glyphs can of course be represented directly by a 32 bit integer, as
they're only composed of a single code-point. However, uncommon glyphs that
would need more than one code-point (because of combining marks) may benefit
from a flyweight approach.

Is this a good use case? Would std::basic_string<flyweight<glyph> > "work" (with
appropriate character traits)? Could I also get boost's regular expressions to
operate on these strings?

Kind regards,
