Oops; another case of the gmail curse. And then my sending the reply to Ray 
alone. Anyway, here's most of Ray's response and then mine.

Yeah, even if the Oa-Oa-Lahahan had endless recursion, what use would they 
make of it? I know that I know that I know that I know that P! Barring Jaako 
Hintikka, no one needs sentences like that.

As for Mwa... I don't think there is any situation that English and Plogl 
can relate that Mwa cannot. I think there are a number of English sentences 
that would come out... err... "badly", but I think it would still translate. 
Let's take "The man who killed Rao's brother escaped to the place where we 
caught the monkey who stole Rao's hat." In Mwa's flat structure, that might 
come out as,

"Rao had a hat. A monkey stole the hat. We caught it at a place. Rao also 
had a brother. A man killed him. The man escaped to that place."

All the facts are there, but something is... lost? "No one knows that I know 
that the Dean knows nothing." This one is problematic.

1. The Dean knows nothing.
2. I know this(1).
3. No one knows this(2).

Once we have the ability to refer to entire sentences/clauses, we get 
something that's equivalent to recursion on some level. Or maybe we don't. 
I'm not sure.

Many of these expressive difficulties can be dealt with via fixed-depth 
recursion. So long as infinite recursion isn't allowed, we can get away with 
a sub-tree structured grammar. But let's wait until language #3 of Aohutl 
for that!

It's a remnant of a pagan past of which they should repent, like unto the 
Hebrews repented of their Proto-Semitic /K/! Repent of thy godless phonemes, 
lest thou pass not the oral exams on judgement day!

Actually, I always include lateral fricatives in whatever language sketch 
I'm playing with, just for their versatility. You just can't beat final -tK 
and -kK. (Or initial Kt- and Kk-!) They're one of the sounds I can't do 
without.
