yes

it would be
def foo (x) {
  def val1 = (
     def r = a + 5;
     x+ r
  );
  val1 + x
}

(note that there was an error in your example:  'let r = r + 5', I
used 'def r = a + 5')

I remember there was some bug with nested variables some time ago, but
I guess it is already fixed and the above code should work.
