How can I make an expresion unique? That is, I want it to copy the
thing it references not just increment the reference. I envision
something like the following pseudocode:
symbol x("x");
ex a = pow(x,2)+2*x+1;
ex b = a; // make b reference the same thing as a
b.make_unique(); // make a new copy of a and reference it with b.
Thanks.
