Really? I have to resort to unsafe??

module test;
 safe: // nope. no can do.

void main()

     auto dFiles = dirEntries("", "*.{d,di}", SpanMode.depth);
     foreach(d; dFiles)
         writeln(d.name);

Well it can't be "truly" safe since it requires a call to the 
system to retrieve the directory entries.

While yeah, from common sense it's most likely safe from the 
perspective of a user, then it's not true safety as there are no 
safety guarantees as it's an external call.

I would argue that D should move towards marking certain system 
functions as trusted.
