63+-- | A @Builder@ is an efficient way to build lazy @Text@ values.

68+-- Internally, a builder constructs a lazy @Text@ by filling arrays

69+-- piece by piece. As each buffer is filled, it is \'popped\' off, to

70+-- become a new chunk of the resulting lazy @Text@. All this is

71+-- hidden from the user of the @Builder@.
