This PR fixes an issue introduced bug #6125 where an `inductive` or `structure` with an autoimplicit parameter with a type that has a metavariable would lead to a panic. Closes #7788. This was due to switching from `Term.addAutoBoundImplicits'` to `Term.addAutoBoundImplicits` and not properly handling metavariables in the parameters list. To fix this, now the inductive type headers record the abstracted type and the number of parameters, rather than record the parameters, the type, the local context, and the local instances. A benefit to this over `Term.addAutoBoundImplicits'` is that the type's parameters do not appear twice in the local context. |
