Which are really either
(literal_text, None, None, None)
or
(None, field_name, format_spec, conversion)
I can't help thinking that these two return types shouldn't be
alternatives that both pretend to be 4-tuples. At the least, they
should be
"literal text"
vs
(field_name, format_spec, conversion)
but you might want to take inspiration from the "tail" of an
elementtree node, and return the field with the literal next to it as
a single object.
(literal_text, field_name, format_spec, conversion)
Where the consumer should output the literal text followed by the
results of formatting the field. And yes, the last tuple would often
be
(literal_text, None, None, None)
to indicate no additional fields need processing.
