I've been thinking about adding a feature to Path::Class that lets you
perform an action in a certain directory, and be guaranteed of being
back where you started afterwards. Hopefully could use fchdir() to be
bulletproof.
The possible interfaces include:
$dir->do_something( \&what_to_do );
or the DESTROY trick like yours:
{
my $sentinel = $dir->scoped_chdir();
...do your stuff...
}
The ideal situation would be if we could hook into perl's actual
scoping mechanisms and eliminate the sentinel:
{
$dir->local_chdir();
...do your stuff...
}
but that's probably out of my ken.
