If a function is @safe then the debug {} calls all remain required to also
follow that requirement as well.

void pureSafe() @safe pure {
    debug {
        writeln("Debugging info!");
    }
}
Error: safe function 'pureSafe' cannot call system function 'writeln'

 Marking the function as @trusted (although works) when the non-debug code is
provably @safe seems like a bad approach just for debugging. Debug scope should
break constraints and limitations for debugging purposes.
