I already did that. I ran it on the Cookbook code.
Yes, some things didn't work out for such reasons as you
state.
That's not the point.
The point is that what you suggest is too much work. You aren't
ever going to get people to add all your gratuitous lint-happiness inserts
to all their docs.

Too complicated. Don't make people change anything. Simply -cw syntax
check anything you can, and don't try to incite a revolution or onerous
burdens worrying about the fringe cases. It's not important enough.
