in reply to comparing nested data structures

So how is dumping the structures as text (which has to traverse the structures in any case) then parsing the text to recreate some internal representation to allow comparison of the structures going to be faster than a direct comparison?

True laziness is hard work

    Well dumping and diffing is done by XS-modules and the dumps can be stored in advance. (BTW: dumping is meant for persistence)

    So what are the alternatives you offer?

      If the dumping and diffing can be done using XS, then so can the recursive comparison.
        Dumping and diffing can already be done using XS (respectively built-ins) in practice.
