Plz note: the data you posted is not a valid serialization of a HoH!

The only way I see is to assign the data to a tied hash, which automatically reacts on collisions...of course all nested hashes need to be tied too.

something like 

my $datastring =slurp $file;
tie %h, "CollisionHash";
eval "\%h = $datastring"

Not sure of this works, and I don't wanna trie to implement it for such a "unique" requirement...
