I agree with dragonchild that this is very domain specific.

Moreover, I wonder whether there's really a sufficiently general test-module here given all the combinations. In most cases, I suspect that a short user function at the top of the test file or in a fixture file would be clear and avoid adding an extra dependency.

Alternatively, instead of writing a new module, how about adding these as options to Test::Differences? Or perhaps adding a generalized callback to filter input before making the comparison?
