It should be possible for one to add a special comment at the end of a line which disables error checking for that line.

As an example of where this is helpful, the following python code-snippet shows up as having an error (on the first return line), when in fact it does not:

    def amethod(self):       
        deltas=(0,6,12,18,24)
        def sgen(*endpoints):
            endpoints = [pt-18 for pt in endpoints]
            return somefunc(*endpoints, deltas=deltas)
        
        return self.othermethod(sgen)


The bottom line is that there will always be room for bugs in the error-parsing code, so when a human knows better than the parser, s/he should be able to tell it to shut up.
