-0. improve the use of [comp] for composition of functions with continuations

 1. stateful maps/sets modules (hashtbl?)
 
 1. Check the occurrence of visitors like visit_AEndedMutLoan: the parameters are
    sometimes inverted!

-2. set of types with mutable borrows (what to do when type variables appear under

-  necessary to know what to return.

 2. check types are not "infinite"
 
 3. in MIR, erased regions are completely erased (no list of erased regions...):
