** Description changed: IMPACT: Python 3.8 has started to emit warnings for code that confuses equality and identity. For more background see https://adamj.eu/tech/2020/01/21 /why-does-python-3-8-syntaxwarning-for-is-literal/ While it is just a warning, it is very visible when running ansible on focal for example, to the point of making the output incredibly hard to follow. Furthermore, the indifference between identity and equality might be creating true bugs as discussed in above blog entry. It seems advisable to fix this incorrect code when found. TEST CASE: tbd REGRESSION POTENTIAL: - tbd + The current code checks for identity via "is" and and "is not"...
