LOL. Personally, it's a feature that I avoid like the plague, because I hate
it when my programs stop working just because I updated dmd (which would be
bad enough for a normal user, but it's particularly nasty when you're
frequently following master and making local changes, because you're working
on Phobos, druntime, and/or dmd). But yeah, when I saw the difference in
size that H.S. Teoh was seeing, my first thought was that one was probably
using Phobos as a shared library while the other was using it as a static
one.
