I was thinking of a case like this:

  print *, (-p)

Where p is invalid.  We need to drill down to run the check on it.

I also found I get a regression with integer_exponentiation.f90 if we do not 
drill down. This turns out to have a substatial mix of operators.  Interesting 
test case.

Thanks for review.
