Agree, although this currently really is a bad default. Having 
all symbols visible by default can lead to really long shared 
library load times especially with template heavy code. I've seen 
reports of shared libaries using boost in c++ having load times 
of 60 seconds and above due to the number of visible symbols.

Ideally we should end up with visibility hidden being the default 
and only making symbols visible which use "export", because that 
is what it was designed for in the first place.
