I love regexps, so I create Perl code from your data and eval it. Just make sure no-one can add Perl code to your data... 
use strict;
use Data::Dump qw[ pp ];

my %hash;
while(<DATA>) {
    chop;
    s/\s*(_|->)\s*/\"\}\{\"/g; # "_" or "->" creates a new level in th
+e hash
    s/(.*)\{/\1=/;             # replace rightmost { with =
    eval( '$hash{"'.$_.'";' ); # put into hash
}

pp \%hash;
