Merging the two indeed seems appropriate.

FWIW, I've read the other thread [1] and agree with Stefan's view 
that circular structures should be handled correctly by the 
compiler. I believe the example with `cycle-pure' shows that this 
is both useful and necessary, since circular structures can appear 
even without being directly present in the source code as 
literals, e.g. after compiler optimizations (which seems to be the 
case here, although I haven't confirmed it 100%).
