constexpr support would require the underlying container (std::vector)
to be constexpr as well, in fact since new (variable sized) storage is
required, I don't see how that would be possible at all..... you could
as someone suggested have a fixed storage polynomial class with
multiplication yielding a different type... any non-trivial manipulation
would lead to a complete explosion of template instantiations though.
