iteration over directories is unsafe

[forkit via Digitalmars-d-learn]

It is not possible to do a simple iteration over directories in 
@safe mode.

Really? I have to resort to unsafe??

//----

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

import std;

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