Hi,

Can I have a `break` option when using `dirEntries()`  (similar 
to `break` in a loop)? I want to study sub-directories but if 
any sub-directory matches my criteria I don't to look further 
into their subdirectories

```
  <working-dir>
     A/   -> matches criteria, stop here, go to next directory 
(B)
     B/   -> doesn't match criteria, will look at its 
sub-directories (BX, BY,...)
       BX
       BY
```

Thanks a lot

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`.
