Rejecting them is not a matter of principle.  It's just that all 
existing code assumes that the references graph is acyclic (hence the 
segfault in the garbage collector).  So supporting this would be a lot 
of work.  If we want multiple output support anytime soon, it's better 
not to do this.

Of course, in the future, if we *do* decide to support it, we can just 
drop the check.
