fields as :class:`For` and :class:`With`, respectively. Only valid in the
body of an :class:`AsyncFunctionDef`.

of :class:`ast.operator`, :class:`ast.unaryop`, :class:`ast.cmpop`,
:class:`ast.boolop` and :class:`ast.expr_context`) on the returned tree

occurrences of the same value (e.g. :class:`ast.Add`).
