Maybe you can use one of the B:: modules. I have only used them a couple of times, but it seems like they do the reflection that you are looking for. You end up in the internals because that's where the structure is.
For example:
use B::XPath;
sub some_function
{
my $struct =
[
'whaa!',
undef,
[
undef,
undef,
{
foo => 3
}
],
{
bar => 'baz'
},
];
}
my $node = B::XPath->fetch_root( \&some_function );
print_children($node, 0);
sub print_children
{
my $node= shift;
my $indent= shift;
foreach my $child ($node->get_children())
{
print " " for (0..$indent);
print $child->get_name()."=".$child."\n";
$indent++;
print_children($child, $indent);
$indent--;
}
}
It should work perfectly the first time! - toma
