> Dynamic linking isn't a problem. Rust does not have a stable ABI at present, so practical use of dynamic linking would require falling back to some baseline ABI/FFI for everything that crosses shared-object boundaries (such as the C FFI), or lead to a requirement that a shared object must be compiled with the same compiler version and compile options as all of its users. This seems like it would be a severe pitfall.
