FileException Inconsistency?

[Alex]

Hi,

After too many years of thinking to try D, I'm creating a simple 
directory scanner.  However, I'm already getting some 
"inconistencies" in Exception handling I'm confused by and trying 
to debug.

I'm using Visual D on Windows. DMD 2.110

In the code below, if I leave the writeln(entry.name) or even 
just writeln(".") uncommented, then I get a FileException for 
permission-denied directories as expected.

If I comment these lines out, e.g. to add the entry.name to an 
array, instead I get a Throwable std.file.FileException which is 
not caught as a FileException or Exception.

Is this expected?  How to best handle this?

Thanks

```
module DirScan;

import std.stdio;
import std.file;
import std.algorithm;
import std.array;
import core.thread;

import std.compiler;

int main()
{
     writeln("DirScan\n");
     writefln("Compiler: %s v%d.%03d", name, version_major, 
version_minor);

     string path = "C:\\";

     scan(path);

     writeln("End. Press Enter.");
     readln();
     return 0;
}

void scan(string path)
{
     writeln("-----");
     writeln("PATH: ", path);

     foreach (DirEntry entry; dirEntries(path, SpanMode.shallow))
     {
         try
         {
             writeln(entry.name);
             writeln(".");

             if (entry.isDir)
                 scan(entry.name);
         }
         catch (FileException fe) {
             writeln("File Exception: ", fe);
             readln();
             continue;
         }
         catch (Exception e) {
             writeln("Exception: ", e);
             readln();
             continue;
         }
         catch (Throwable t) {
             writeln("Throwable: ", t);
             readln();
             return;
         }
     }
}
