docs: Get the canonical name for a symbol.
  
          This is the default implementation.
          If the user specifies a name,
          the user-specified name will be used.
  
          When user does not specify a name, we automatically generate a
          name based on the hint string.
  
          Parameters
          ----------
          name : str or None
              The name specified by the user.
  
          hint : str
              A hint string, which can be used to generate name.
  
          Returns
          -------
          full_name : str
              A canonical name for the symbol.
