could you explain the change in the description? also what is happening with the mypy script? |

@NoureldinYosri Added a detailed description and the change to mypy script was a mistake so I've reverted it. |

Fixes #6173
Part of #6097
This leads to a roughly
~4-5ximprovement in performance forcirq.map_operationsandcirq.map_operations_and_unroll. See #6173 (comment) for a detailed use-case specific analysis.The primary reason behind the speedup is to get rid of repeated instantiations of
cirq.Circuit, which was being done for once for every call tomap_func(op, i). The intermediate circuits were constructed mainly for circuit alignment. This PR instead uses the circuit construction strategy similar to the one used inCirq/cirq-core/cirq/circuits/circuit.py
Line 1760 in 95c672a
cirq.Circuitconstructor only once at the end.
