Yeah, it seems like in this age of dirt cheap storage and memory, dynamic linking
is often more trouble than it's worth.  It definitely makes things more
complicated.  When _is_ the tradeoff worth it for dynamic linking?

Also, as far as Phobos being dynamically linked, that would never work well anyhow
because so much of it is templates.
