 ### To-do list
 
-In no particular order. Some of the following might require changes to the Isabelle prover itself.
+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.
