I'm asking because I think we should change the default visibility of D
functions in shared libraries. We want to encourage platform
independent code so good code should use the 'export' attribute
anyway.

Making all symbols public by default and templates is a bad combination
for performance as it stresses the runtime linker. Look at that gcc
page, they managed to create a templated library that takes 6 minutes
to load because of this!
