No. We had a very long discussion about safe-by-default on the forums but failed to reach a consensus.
As I understand it, for safe-by-default to work, either all C libraries would have @trusted D bindings written, or all of them would have to be assumed to be @trusted. Most of the community wanted explicit @trusted annotations, Walter and others favored assuming them to be @trusted (or was it assumed @safe?) was the way to go. So, no safe-by-default at this time. :/
