http://d.puremagic.com/issues/show_bug.cgi?id=3459 Summary: There should be a flavor of file.listdir() that returns a range instead of taking a delegate Product: D Version: 2.035 Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: Phobos AssignedTo: nobody puremagic.com ReportedBy: llucax gmail.com PDT --- This idiom: ---- foreach (f; listdir(some_dir)) writeln(f); ---- is much more simpler, convenient and clearer than: ---- listdir(some_dir, (string f) { writeln(f) }); ---- Which looks more obscure (specially when the callback is more complex. The first idiom was not possible in D1 without allocating an array for the elements, which can be inefficient, but with ranges in place in D2, I think listdir() should use them.
