"Last is first" very much reminds me of the custos/custodes seen often in Gregorian chant notation, which come at the end of a line and are a hint of the first note in the next line (so while your eye is finding the start of the next line, you already know the pitch, even though it typically does not include the syllable).

See e.g. https://lilypond.org/doc/v2.18/Documentation/notation/ancien...
