I read DIP1028. However, my suggestion is somewhat different - it 
is to allow a compiler flag - say -fdefault-safe - such that any 
code that is not annotated explicitly gets a default of @safe. 
Thus anyone using this flag would not need to explicitly annotate 
with @safe. I also suggest not changing the meaning of anything 
other than just defaulting as above.

@live is more complicated I suppose as it can't deal with GC
