Closure from String

Question

How to create a closure from a string?

Like I have a string def formula = "{it * it}"

Now formula is a string and I can't do formula()

how do I define the code block in the string variable formula as a closure?

You can do:

def formula = Eval.me( "{ x -> x * x}" )

formula( 3 )

Obviously the usual warnings about the safety of evaluating strings entered by users apply
