> When having duplicate fields, the repr fails:
> {code}
> In [28]: s = pa.scalar([('a', 1), ('b', 2), ('a', 3)], pa.struct([('a',
> 'int64'), ('b', 'int64'), ('a', 'int64')]))
> In [29]: 0 in s
> Out[29]: True
> In [30]: s
> ....
> KeyError: 'a'
> {code}
> In addition, the contains ({{in}}) operation also shouldn't accept integers
> (this is also the case for non-duplicate fields)
