Not knowing anything about `polymorphic_value`, I welcome a new library
submitted for a review, but I don't see why the review should be
fast-tracked. Fast-tracked reviews are typically performed on something
that the community is very familiar with (not only the concept but the
implementation as well), which basically means it has to undergo a full
review first. That the library is also being reviewed by someone else
(e.g. LEWG) does not mean it has a free entry into Boost.
