Type of declared expert extensions.

The 'context type parameter describes where the extension is expected and the 'payload one what its payload should contain.

  string ->
  'context Context.t ->
  (Migrate_parsetree.Ast_412.Parsetree.payload, 'a, 'b) Ast_pattern.t ->
  'a ->
  ('context, 'b) t

val declare_with_path_arg : 
  string ->
  'context Context.t ->
  (Migrate_parsetree.Ast_412.Parsetree.payload, 'a, 'b) Ast_pattern.t ->
  (arg:Longident.t Loc.t option -> 'a) ->
  ('context, 'b) t

val convert : 
  (_, 'a) t list ->
  loc:Location.t ->
  (string Location.loc * Migrate_parsetree.Ast_412.Parsetree.payload) ->
