    I might be misreading the justification for the feature. Patch 2 is
    talking about tools that need to understand memeory usage to make
    further actions. Also Suren was suggesting "numbering convetion" as an
    argument against.

    So can we get a clear example how is this being used actually? If this
    is just to be used to debug by humans than I can see an argument for
    human readable form. If this is, however, meant to be used by tools to
    make some actions then the argument for strings is much weaker.
