// If we had C++11 template aliases, we could just use this:
//
// template <typename T,
// size_t MinInlineCapacity = 0,
// class AllocPolicy = TempAllocPolicy>
// using Vector = mozilla::Vector<T, MinInlineCapacity, AllocPolicy>;
//
// ...and get rid of all the CRTP madness in mozilla::Vector(Base). But we
// can't because compiler support's not up to snuff. (Template aliases are in
// gcc 4.7 and clang 3.0 and are expected to be in MSVC 2013.) Instead, have a
// completely separate class inheriting from mozilla::Vector, and throw CRTP at
// the problem til things work.
//
// This workaround presents a couple issues. First, because js::Vector is a
// distinct type from mozilla::Vector, overload resolution, method calls, etc.
// are affected. *Hopefully* this won't be too bad in practice. (A bunch of
// places had to be fixed when mozilla::Vector was introduced, but it wasn't a
// crazy number.) Second, mozilla::Vector's interface has to be made subclass-
// ready via CRTP -- or rather, via mozilla::VectorBase, which basically no one
// should use. :-) Third, we have to redefine the constructors and the non-
// inherited operators. Blech. Happily there aren't too many of these, so it
// isn't the end of the world.
