       DirHandle - (obsolete) supply object methods for	directory handles

	   # recommended approach since	Perl 5.6: do not use DirHandle
	   if (opendir my $d, '.') {
	       while (readdir $d) { something($_); }
	       rewind $d;
	       while (readdir $d) { something_else($_);	}

	   # how you would use this module if you were going to
	   use DirHandle;
	   if (my $d = DirHandle->new(".")) {
	       while (defined($_ = $d->read)) {	something($_); }
	       while (defined($_ = $d->read)) {	something_else($_); }

       There is	no reason to use this module nowadays.

       The "DirHandle" method provide an alternative interface to the
       opendir(), closedir(), readdir(), and rewinddir() functions.

       Up to Perl 5.5, opendir() could not autovivify a	directory handle from
       "undef",	so using a lexical handle required using a function from
       Symbol to create	an anonymous glob, which took a	separate step.
       "DirHandle" encapsulates	this, which allowed cleaner code than
       opendir().  Since Perl 5.6, opendir() alone has been all	you need for
       lexical handles.
