If it were @safe, the compiler would accept it.
Looking at the code, I believe there are several casts that the
compiler can't verify but are used safely.

If it's a delegate with an un- at safe destructor (how would that
work? a captured context variable?), then it's already not @safe.
If it's a function, it doesn't have a destructor. If it's a
user-defined type with opCall, that's something to pay attention
to, but it's beyond the scope of the original question.
