[affeldt-aist]

This is just to let you know about a compilation error that we have observed
on Apery's CI: coq-community/apery@18a6456

The error messages reads as follows:

 # File "./refinements/param.v", line 59, characters 0-23:
 # Error: Unsatisfied constraints: simpl_pred.u0 <= simpl_fun.u0
 # (maybe a bugged tactic).

On which version of what?
