In my previous post, i explained how one might use invariant_ring (for
getting a Hironaka decomposition)

Hi, the 'trivial' way to fix it, is to implement a Python function for
SinguleElement called invariant_ring which calls the Singular function,
parses the output and returns a tuple. If you call A.invariant_ring the

Are you actually interested in a Hironaka decomposition? Or are you
looking
