I feel like my planned ad-hoc fixes/hacks would work, but I am planning to take a look at type families and see if I get some inspiration so we can solve this problem at a higher level. |

prop:procedureandprop:evtat the same timecloses #167
The basic idea is 1. we should check
prop:evtin the similar way as we checkprop:procedure, and also we handle their differences correctly via a table + high order functions2. so the structure type rep should store a list of extra types extracted from values for those properties.
