np.array(a)raises a warning:
<python-input-0>:4: DeprecationWarning: __array__ implementation doesn't accept a copy keyword, so passing copy=False failed. __array__ must implement 'dtype' and 'copy' keyword arguments.

array([Fraction(1, 2), Fraction(2, 3)], dtype=object)
But the following do not:
>>> a.to_numpy()
array([Fraction(1, 2), Fraction(2, 3)], dtype=object)
>>> a.__array__()
array([Fraction(1, 2), Fraction(2, 3)], dtype=object)And other numeric eltypes seem not:
>>> b = jl.seval('[1, 2, 3]')
>>> np.array(b)
array([1, 2, 3])>>> np.__version__
'2.3.3'
>>> import juliacall; juliacall.__version__
