[New-bugs-announce] [issue23802] patch: __deepcopy__ memo dict argument usage

[Daniel Shahaf]

New submission from Daniel Shahaf:

In the 'copy' module documentation, it wasn't fully clear to me how __deepcopy__ implementations should treat the memo dict argument.  The attached patch clarifies that __deepcopy__ implementations should treat the memo dict argument as an opaque type.
