UNWRAP

Takes the topmost item and evaluates it as a PumpkinScript values-only program on the current stack

Input stack: vals

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 words, evaluates it (essentially, putting all the data on the stack)

It's particularly useful in conjunction with NONE? and SOME?.
