See #1480 @semorrison We can now use the following commands to trace the rewrite tactic ```lean set_option trace.rewrite true set_option trace.kabstract true ``` When these options are used, Lean will pretty print the subterm selected by the rewrite tactic. That is, the subterm that will be rewritten. This option may help you diagnose what is going on.
