Do you too run into universe inconsistencies?

I did.

I haven't been following your discussion carefully, but I want to point you to the previous thread on this topic for your interest

<http://pauillac.inria.fr/pipermail/coq-club/2005/001726.html>

and in particular Gonthier's reply <http://pauillac.inria.fr/pipermail/coq-club/2005/001743.html>

which lead to the developement on the coq wiki at
<http://cocorico.cs.ru.nl/coqwiki/UntypedLambdaTerms> (see Non-uniform De Bruijn Indices)

and instigated the changes to coq to allow nested datatypes parametrically.
