:meth:`.Clifford.from_circuit` will no longer attempt to resolve instructions whose
|
|
:attr:`~.circuit.Instruction.definition` fields are mutually recursive with some other object.
|
|
Such recursive definitions are already a violation of the strictly hierarchical ordering that
|
|
the :attr:`~.circuit.Instruction.definition` field requires, and code should not rely on this
|
|
being possible at all. If you want to define equivalences that are permitted to have (mutual)
|
|
cycles, use an :class:`.EquivalenceLibrary`.
