A case class with a varargs has a unapplySeq extractor instead of unapply. When we type an unapply, in typedUnapply, we first look for unapply methods before unapplySeq methods. But when searching for unapply, if a class method isn't found, then an extension method is looked for, which causes context implicits to be cached. The bindings from a pattern (such as from an unapply or unapplySeq extractor) are added to the context in indexPattern. But Context's `implicitCache` doesn't account for the scope changing. I opted for giving the body its own scope context, rather than making indexPattern reset the context implicits cache. [Cherry-picked 69f5f73]
