@unsafe was suggested (I think by Don) to provide symmetry with @safe
and @trusted. This is a good point, but I'm starting to think that
@unsafe is not a good idea.
For example, one could make an entire module safe with:
-------------------
module foo;
@safe:
[...]
-------------------
And an observer could conclude that foo only contains safe and trusted
code. But if @unsafe could override, he has to delve into it looking for
@unsafe as well.
Furthermore, why would a safe module wish to expose unsafe functions?
Shouldn't the programmer instead be obliged to produce trusted functions
in it?
