ISSUE-117 is (a) much broader in its scope than ISSUE-119, and (b) it is not 
clear at the moment whether completely dropping the comprehension principle 
for self restrictions is the only possible technical solution for this 
problem.

Then it makes sense to start with ISSUE-119, which *needs* a solution. The 
more general ISSUE-117 may or may not become a relevant topic /after/ 
resolving ISSUE-119.

The only comment by me on this will be that there will not be any comment by 
me on this. :)
