Can I skip sub directories with file.dirEntries() ?

I'd just use dirEntries with SpanMode.shallow in combination with 
filter either in a loop or a recursive function like below.

void foo(string path = "path")
{
     foreach(e; 
dirEntries(path,SpanMode.shallow).filter!(myCritreia(paramters)))
     {
         if (e. isDir)
             foo(e.name); // recurse
         // do other stuff
     }
}

you will loop over all subdirs of "path" that satisfy 
`myCritreia`.
