I do not understand his translations into English. The nature of a change, any change, is that it may invalidate old texts, either Lojban ones or English explanations.

My change, as captured in the phrase "'lo' has widest scope", is precisely in the expansion of Example 6, which now becomes: [su'o] da poi nanmu naku zo'u da klama le zarci which is equivalent to: naku ro da poi nanmu zo'u da klama le zarci which denies that all men go to the store, which is equivalent to affirming that some men do not go to the store. -- John Cowan sharing account for now e'osai ko sarji la lojban.
