The idea is that we should seldon need to unfold theorems. The convertability checker should use that. When the convertability checker was implemented, theorems were opaque in Lean. So, this hint was not needed. This modification is another workaround for the performance problem with the migrate command at library/data/real/division.lean. This solution is better than applying proof irrelevance eagerly because it also addresses similar problems in the HoTT library which does not support proof irrelevance. This commit also enables the conv_opt for all theorems. |
