If ``atype`` is the dtype passed in by the user and ``adesc`` is the
description of an existing table, wouldn't ``atype == adesc._v_dtype`` do the
trick? dtypes can be compared for structural and field name equality, and
according to the documentation of ``Description``:
_v_dtype
The NumPy type which reflects the structure of this table or
nested column. You can use this as the ``dtype`` argument of
NumPy array factories.
