code: def from_maybe_starargs(cls, args, use_comma=True):
          
          if len(args) == 1:
              if isinstance(args[0], cls):
                  return args[0]
              elif isinstance(args[0], (list, tuple)):
                  return cls(args[0], use_comma=use_comma)
  
          return cls(args, use_comma=use_comma)
docs: If `args` has one element which appears to be a list, return it.
          Otherwise, return a list as normal.
  
          Mainly used by Sass function implementations that predate `...`
          support, so they can accept both a list of arguments and a single list
          stored in a variable.
