What's the official status of shared libraries in dmd 2.063? Is it already deemed stable or can there still be breaking changes for dmd 2.064? 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! http://gcc.gnu.org/wiki/Visibility http://software.intel.com/en-us/articles/software-convention-models-using-elf-visibility-attributes http://www.technovelty.org/code/why-symbol-visibility-is-good.html
