DirHandle - Port of Perl's DirHandle
use DirHandle;
with Dirhandle.new(".") -> $d {
while $d.read -> $entry { something($entry) }
$d->rewind;
while $d.read(Mu) { something_else($_) }
$d.close;
}
The DirHandle object provides an alternative interface to the opendir, closedir, readdir, telldir, seekdir and rewinddir functions.
The only objective benefit to using DirHandle is that it avoids namespace pollution.
Since Raku does not have a concept like void context, one needs to specify Mu as the only positional parameter with read to mimic the behaviour of DirHandle.read of Perl in void context.
The Perl version of DirHandle for some mysterious reason does not contain methods for performing a telldir or a seekdir. The Raku version does contain equivalent methods tell and seek.
