Describe the issue:

According to the array-api standard for all:

out (array) – if a logical AND reduction was performed over the entire array, the returned array must be a zero-dimensional array containing the test result. Otherwise, the returned array must be a non-zero-dimensional array containing the test results. The returned array must have a data type of bool.

Thus, I expect the return from np.all to definitely be an array. This is not the case .

Reproduce the code example:

>>> import numpy as np
>>> x = np.array([1.0, 2.0])
>>> res = np.all(np.equal(x, x)) # res is np.True_ here, it should be something like np.array(True, dtype=bool)
>>> assert isinstance(res, np.ndarray)

Error message:

      3 res = np.all(np.equal(x, x))
