2015-03-25Fully fixing bug #3491 (anomaly when building _rect scheme in theHugo Herbelin
presence of let-ins and recursively non-uniform parameters). The bug was in the List.chop of Inductiveops.get_arity which was wrong in the presence of let-ins and recursively non-uniform parameters. The bug #3491 showed up because, in addition to have let-ins, it was wrongly detected as having recursively non-uniform parameters. Also added some comments in declarations.mli.
2015-03-25Another example about the consequence of a wrong computation of theHugo Herbelin
number of recursively uniform parameters in the presence of let-ins. In practice, more recursively non-uniform parameters were assumed and this was used especially for checking positivity of nested types, leading to refusing more nested types than necessary (see Inductive.v).
2015-03-24Fixing computation of non-recursively uniform arguments in theHugo Herbelin
presence of let-ins. This fixes #3491.
2015-03-24Fixing wrong rel_context in checking positivity condition.Hugo Herbelin
Parameters were missing in the context, apparently without negative effects because the context was used only for whd normalization of types, while reduction (in closure.ml) was resistant to unbound rels. See however next commit for an indirect effect on the wrong computation of non recursively uniform parameters producing an anomaly when computing _rect schemas.

2011-05-26Partial fix for accepting bound variables with same name as implicitherbelin
parameters of inductive types when these variables cannot bind the conclusion of the inductive type (done for "return" predicates but still to be done for non strictly positive binding occurrence, as e.g. in "Set Implicit Arguments. Inductive I A:A->Prop:=C a:(forall A, A)->I a." which should morally be accepted but is not). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14159 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-08-11Ensures that let-in's in arities of inductive types work well. Maybe notherbelin
very useful in practice but as soon as let-in's were not forbidden in the internal data structure, better to do it. Moreover, this gets closer to the view were inductive definitions are uniformly built from "contexts".
