Stochastic grammar of stochastic grammar

Zellig Harris observed that the metalanguage is in the language; see for a recapitulation Harris' The Background of transformational and metalanguage analysis, in The legacy of Zellig Harris: language and information into the 21st century, Vol 1, 2002. (By the way, there is a very interesting article by Maurice Gross, Consequences of the metalanguage being included in the language, in the same book; the author finally debunks the use of VP in syntactic analysis, a long overdue pronouncement).

How would a stochastic grammar that contains itself look?

No, wait a minute, that's too easy. How would a stochastic grammar that can learn itself look?

That would resemble more to Harris' observation. I can tell a child, or a foreigner new with the language, "That's not the way this verb is used". The stochastic grammar should be able to say, "That's not the way a stochastic grammar is built". How do we say that in stochastic grammar land?
