In order to support object wrappers/proxies like
weakref.proxyand rapidsai/dask-cuda#451, this PR implements type checking usingx.__class__instead oftype(x).This PR shouldn't change any semantic other than the support of proxies.
We did something similar in Dask, for a detailed discussion of the difference between
__class__andtypesee dask/dask#6981This change is motivated by rapidsai/dask-cuda#610
