"Block" example from documentation does not evaluate

[Frizzled]

https://cortexjs.io/compute-engine/reference/control-structures/#block-and-if

    const expr = ce.box(["Block", ["Tuple", "c", 5], ["Multiply", "c", 2]])
    console.log(expr.evaluate().valueOf()) // returns: ["Block",["Pair","c",5],["Multiply",2,"c"]]

Works now, although the syntax has changed slightly:

["Block", ["Assign", "c", 5], ["Multiply", "c", 2]]
