}
Add has_default to GenericParamDefKind::Const This currently creates a field which is always false on GenericParamDefKind for future use when consts are permitted to have defaults Update const_generics:default locations Previously just ignored them, now actually do something about them. Fix using type check instead of value Add parsing This adds all the necessary changes to lower const-generics defaults from parsing. Change P<Expr> to AnonConst This matches the arguments passed to instantiations of const generics, and makes it specific to just anonymous constants.
