 ### To-do list
 
-In no particular order. Some of the following might(?) require changes to the Isabelle prover itself.
-
-- [ ] Dedicated type information data
-- [ ] Tactic-based term elaboration has (at least) two problems:
-        1. `assume(s)` clauses don't accept schematic vars, and
-        2. it often results in overly-flexible subgoals that the typechecker doesn't solve.
-      Will need an elaborator integrated into Isabelle's syntax checking.
-- [ ] Proper handling of universes.
-- [ ] Inductive type definitions.
-- [ ] Recursive function definitions.
-- [ ] Higher inductive type definitions.
+In no particular order.
