Yeah. I'm not sure how well @safe is implemented in general, but IIRC, it's 
not fully implemented yet - though it certainly works well enough to use in 
many cases. However, one of the biggest problems is essentially the same 
problem that we have with const, and that is that not enough stuff in druntime 
and Phobos uses it where it should. Case in point: Exception isn't marked with 
@safe, pure, or nothrow, and it probably could (and probably _should_) be 
marked with all three. Attribute inferrence for templates has helped a lot 
with the problem, but there's still plenty of non-templated stuff which needs 
to be fixed up to work properly with @safe, pure, and nothrow.
