[comp.lang.icon] Dereferencing

Yes, Beth was absolutely right about the way to fix my example of a generator
that returns variables.
 
I find it interesting that Icon attempts to preserve the "variable"-ness of
a returned entity, dereferencing it only if it has to.  But I can't think of a
way of moving a variable in the other direction: from caller to callee.  Not
only does Icon have call-by-value---there doesn't seem to be any way to
circumvent it.  Or is there------?
