docs: r"""Like `some`, but only returns `True` if all the elements of `iterables`
      satisfy `predicate`.
  
      Examples:
      >>> every(bool, [])
      True
      >>> every(bool, [0])
      False
      >>> every(bool, [1,1])
      True
      >>> every(operator.eq, [1,2,3],[1,2])
      True
      >>> every(operator.eq, [1,2,3],[0,2])
      False
