No. It's not, they are pointers to different object.
Technically you could do
val a = ref 5;
val b = a;
That would work.
Question
I have two refs in SML:
val a = ref 5; val b = ref 6;
Currently a = b evaluates to false. Is it possible to somehow assign variable b so that a = b evaluates to true? Thanks
