Warnings for numerical operations on logical objects

I'm not sure whether the compiler is required to diagnose this sort of silliness or not with /stand, but it would be nice if it did.

PROGRAM LogicalOperations
  IMPLICIT NONE
  LOGICAL :: la, lb

  la = .TRUE.
  lb = .FALSE.

  PRINT *, -la
  PRINT *, +la
  PRINT *, la + lb
  PRINT *, la - lb
  PRINT *, la * lb
  PRINT *, lb / la
  PRINT *, la ** lb
END PROGRAM LogicalOperations
