Also, there is the big unresolved topic of symbol visibility, see 
e.g. http://wiki.dlang.org/DIP45 and the associated discussion.

I'm afraid we will repeat C++'s mistakes here and shoot ourselves 
in the foot big time if we keep symbols visible (i.e. exported 
from shared libraries) by default. The impact of that on (link 
time) optimization opportunities and, for big libraries, load 
times is absolutely non-negligible.
