Update: What I didn't specify, but perhaps should have, is that parts of the data structure are blessed object references, and I want to compare the guts of the objects.

Conclusion:

ModuleConclusion
Data::DumperHashes not consistently serialised
Test::MoreOnly does a shallow comparison.
Tie::IxHashSolves a different problem. Anonymous hashes cannot be tied
FreezeThawOnly copes with shallow structures
Struct::CompareDoes not handle references
Recursive comparison by thraxilDoes not handle object references
Data::CompareDoes not handle references

Conclusion: either fix Data::Dumper or roll my own compare routine :-<.

Update 2: I have been looking further at Test::More. There are numerous versions floating about, owing to the way in which people have used it to package up their tests in their own modules.

The definitive Test::More on CPAN has a function eq_hash, which suffers from the same syndrome as Data::Dumper when it comes to ordering of keys.

Update 3: simonm++ The module Class::MakeMethods::Utility::Ref does the business! Shame about the name - something as useful should not IMO have a module name 4 levels down, with no clue as to what it can do.
