+Subject: [PATCH]  Fix interpret decimal.Decimal object as an integer
+
+Ref: https://docs.python.org/3.8/whatsnew/3.8.html
+
+Many builtin and extension functions that take integer arguments will
+now emit a deprecation warning for Decimals, Fractions and any other
+objects that can be converted to integers only with a loss (e.g. that
+have the `__int__()` method but do not have the `__index__()` method).
+In future version they will be errors. (Contributed by Serhiy
+Storchaka in bpo-36048.)
