Research direction
The issue names no repository files or tests. Start by reviewing the proposed tolist behavior against NumPy and PyTorch and the existing array API conversion rules; done means the standard has an agreed definition for converting zero-dimensional and nested arrays to Python representations.
Written by the indexing model from the issue text.
Description
I think (correct me if I am mistaken) that currently the only way to convert an array object back to a Python representation is to call float, int, bool, etc on 0D arrays. This requires that the user knows the appropriate function to call and does not offer any standard way to retrieve the underlying Python object when the library has additional dtypes, such as object in NumPy.
Moreover, as there is no tolist in the standard, it is also not possible to obtain a list representation of the array (from which the Python object could be retrieved).
I propose to add tolist to the standard, as defined in NumPy and Pytorch to deal with these cases. Although the name is a bit misleading (because for 0D arrays there is no list at all), I think that prior art justifies reusing that name.
