Project-wide **PEP-agnostic type hint getter utilities** (i.e., callables

    '''
    **Representation** (i.e., machine-readable string returned by the
    :func:`repr` builtin when passed this hint) of this PEP-agnostic type hint.

    This getter is memoized for efficiency. Indeed, since the implementation of
    this getter trivially reduces to just ``repr(hint)``, memoization is the
    entire reason for the existence of this getter.

    Motivation
    ----------
    **This getter should always be called to efficiently obtain the
    representation of any type hint.** The comparatively less efficient
    :func:`repr` builtin should *never* be called to do so.

    Parameters
    ----------
    hint : object
        Type hint to be represented.

    Returns
    ----------
    str
        Representation of this hint.

    # Return the machine-readable representation of this hint.
