Checks whether the given range is compatible with this one. We err on the side of caution. E.g. if we have

    method(x)
 

and the parameter declaration says that x is between 0 and 10, and then we have a parameter which is known to be in the range 5 to 15, here we consider this a compatible range; we don't flag this as an error. If however, the ranges don't overlap, *then* we complain.
