> Beam currently runs Python tests in 4 version of Python: 2.7, 3.5, 3.6, 3.7. Some Python 3 tests may include code that is considered incorrect syntax in older versions of Python, and such test may break test suites that they are not intended for, see an example: [1] 
> We use `exec` as work around in (very few) tests , example: [2], but it is less convenient to work with such code, for example it is harder to debug or work with in IDE. 
> We should find best practices to deal with this problem and introduce a solution to the Beam .
