ToExpression[input] gives the expression obtained by interpreting strings or boxes as 
    Wolfram Language input. 
ToExpression[input, form] uses interpretation rules corresponding to the specified form. 
ToExpression[input, form, h] wraps the head h
     around the expression produced before evaluating it.

It would be useful also for the new version of iwolfram.
