uproot.writing.identify.to_writable(obj)

  Converts arbitrary Python object `obj` to a writable uproot.Model if possible; raises `TypeError` otherwise.

  This function is a series of rules that defines what Python data can or cannot be written to ROOT files. For instance, a 2-tuple of NumPy arrays with the appropriate dimensions is recognized as a histogram, since NumPy’s `np.histogram` function produces such objects.

  This series of rules is expected to grow with time.
