Wrote:  you generate an object with a tree structure (+ (+ 2 3) 1) because for the parser + is a binary operator, but for the (future) CAS to operate properly, it flattens the tree to (+ 2 3 1), which makes it simpler to simplify terms, search for expressions, cancel out terms, etc.
Your fraction '2/3' is converted after EVAL to '2*INV(3)' per the rules above. What you get from OBJ-> is one level expansion of the main operator. Perhaps OBJ-> should convert to canonical form always before expanding, so you get consistent results every time.

Other than that, everything works as designed.

Interesting. I'll have to rethink how I do things a bit, then. ->NUM followed by ->Q should do the trick.

Will we get access to the full tree, like the old ->LST and ->ALG commands? Very useful at times.

I'll recreate the list and email it to you.
