And also ‘ma anpa li kama kiwen lete’ and so on, so it isn’t a Y/N question form (but neither are the others, really).
‘taso’ is not followed by ‘la’ but stands alone as a conjunction, like ‘anu’ (but ‘anu’ doesn’t need a period, in spite of some usage)
‘anu seme’ comes at the very end of a sentence, after the prepositional phrases , if any, so won’t be buried.
“question coming” seems very different from conditions and context.
It is concise and it is nice to put it out front (like Esperanto and Lojban (sometimes), though this latter sounds like trying to be English again.
An interesting proposal, but not an obvious candidate for inclusion (for one, thing, we already have a number of solutions to this problem).
