@martimlobao thanks a lot for this contribution.
The modification looks good to me however it would be quite interesting to have unit tests that show the current behaviour of pylint when enum class have with ... as structure.

@martimlobao Thanks for the PR! Unfortunately the root cause of the issue was our Enum transform, which was dropping the attributes that it could not understand from the class's locals., such as those for With nodes.

78e56c6 should fix this properly.

@PCManticore Awesome, thanks for fixing the real underlying issue then!
