-----------------------------------------------

[~lhoestq] Thanks for the report. I agree it would be good to enable this as well for consistency.

> Hi everyone !
> Currently one can create a BooleanArray using these ways:
> {code:python}
> pa.array([False, True, True, False])
> pa.array(np.array([0, 1, 1, 0]), type=pa.bool_())
> pa.array([0, 1, 1, 0]).cast(pa.bool_())
> {code}
> But creating it this way fails:
> {code:python}
> pa.array([0, 1, 1, 0], type=pa.bool_())
> {code}
> {code}
