Well it was that pesky intuitive part of my brain that never bothers
to explain itself and gets me into so much trouble with people who
want formal rigor - BUT if there was a moral it would have been
something like this: Module systems are a problem because they want to
make it appear that there are many top-levels and that composition of
top-level environments is simple. That composing TLs should be even
possible seems like just so much typological nonsense to me. LAMBDA
keeps the scope (and hence type complexity) nicely bounded. But I've
already flogged that dog enough :)

Gah! Don't let a reverse-engineered moral get in the way of a good sing :)
