Description of the problem

The following code does not raise an error, and the behavior is undocumented.

Section Test.
Variables (b : bool) (n : nat) (All : unit).
Collection n := b.

Lemma foo : True.
Proof using n.
trivial.
Qed.

Lemma bar : True.
Proof using All.
trivial.
Qed.
End Test.

Check foo : bool -> True.
Check bar : bool -> nat -> unit -> True.

This is very low prio, but it usually happens that when touching Prims or some other file high in the dependency graph, we get spurious diffs in many other files. Since we check-in the snapshot, and we need to have it up-to-date, we get very verbose commits when nothing relevant changed. Plus, when something did change, it's hard to spot.

Example: I removed a few lines in prims and get things

It would be a nice convenience to allow the syntax

import M as _.

This would have the effect of checking module M but not adding any of its names to the context of the importing file. The use case for this is if you want to have a single Cedille source file that includes a bunch of other files, without having to worry about namespace clashes. This would be handy for testing. One can achie

This issue is not urgent. I open it to keep it in mind.

Many tools use http://www.sphinx-doc.org/ now for their doc, including Coq. See https://coq.inria.fr/distrib/current/refman/ . It seems to be automatically generated from html and http://docutils.sourceforge.net/rst.html files in https://github.com/coq/doc.

Perhaps we should do the same to get a better rendering of the doc.
