Do you also think reusing an *extern* name in a local block is "plain bad
design"?  I can't see the difference.  I agree you should avoid overloading
names, but the idea behind the overloading classes is so you can confidently
define local variables which are guaranteed to be independent of the rest of
your project.  Not having to worry about a typedef defined in some 'include'
file improves modularity.
