[docs] [issue24659] dict() built-in fails on iterators with a "keys" attribute

[Christian Barcenas]

Christian Barcenas added the comment:

Should have clarified that the specific issue that is outlined in #5945 is that PyMapping_Check returns 1 on sequences (e.g. lists), which would mean something like x = [('one', 1), ('two', 2)]; dict(x) would fail in 3.x because x would be incorrectly evaluated as a mapping rather than as an iterable.
