# Pins: copy.copy and copy.deepcopy both return an independent clone.
# Mutations to the clone don't affect the original.
#
# Documented divergence: this interpreter's owned-value model makes
# copy.copy and copy.deepcopy semantically identical — there's no
# reference identity to share between shallow copies. CPython's
# `shallow[0].append(x)` mutates the original because shallow shares
# inner references; ours does not.
