When I use strict; I get the error Global symbol "@tree" requires explicit package name. This is a good clue.

When I change 

my $node1 = ${$tree[0]}{name};

[download]
to 
my $node1 = ${$tree->[0]}{name};

[download]
everything works.

$tree[0] is the zero'th element of @tree.

$tree->[0] is the zero'th element of tree that is referenced by $tree.
