There are a number of good reasons to switch to explicit export,
i.e. normal symbols use hidden visibility and exported symbols use default
visibility.
- Windows compatibility
- less performance impact for PIC as only exported symbols require an
indirection
- faster symbol lookup reduces the load time
- more possibilities for link time optimizations
- inlining visible functions breaks interposition

NB:
As of now libphobos2.so exports 14100 symbols and 87139 with unittests compiled
in.
