Thank you for the feedback (and for confirming there is not a standard/build-in solution to do this). My @test_data should contain only hashes as in my example (and probably with a bit of cleaning in the pre-process) always with the two (identical) keys. The values of the hashes should any digit/literal (words and so on), possibly containing also characters such as ,|'". (unicode strings). The size of @test_data can be big (100.000 hashes), but performance (time) is not an issue in this context.
