Review Comment:
Yup. Poor-man's constant folding using an obvious hack - infoset to be a
fake infoset that just throws if you try to access any method on it. Eval
expression. No infoset access means it can compute the value. If it touches the
infoset, it throws, and determines therefore that it can't constant-fold the
expression.
