>>3. With this in mind then Bjorn's new checks are probably a bad idea, the warnings become even more ad hoc and difficult to understand. I wonder if maybe some of the existing warnings should be removed. I still say that many of the warnings give very little and some are a right pain.***

Warning about exporting variables out of if/case/receive statements is 
one one I would have left in as it is clearly dangerous. :-)

Fine, but why force it on me by default? Leave the warning in there but 
let people who want it turn it on explicitly. Having it as default means 
you are trying to enforce a certain style.

Defintely add an option to turn warning about unused functions on and 
off, but have the default value OFF.
