Takes the topmost item and evaluates it as a PumpkinScript values-only program on the current stack
Output stack: all the values
UNWRAP is a "safe" cousin of EVAL. It takes a closure and as long as it does not contain any instructions, evaluates it (essentially, putting all the data on the stack)
PumpkinDB> [1 2 3] UNWRAP 1 2 3
Runtime allocation during parsing
EmptyStack error if there is less than one item on the stack
InvalidValue error if there are instructions in the item
works : [3 2 1 ] UNWRAP. empty_stack : [UNWRAP] TRY UNWRAP 0x04 EQUAL?.
