Ok, well it seems like everyone has got their own ideas on this.  
Guess we can't expect to see too much agreement in a hurry.

But no comments on the "file_finder"? (the name is based on an MFC 
class with similar functionality, I'm open to better ideas)

It doesn't allow access to file info (size, date/time etc) because 
glob doesn't do this, and you get this easily enough once you have a 
filename.  I think something like this needs to be integrated with 
the directory iterator stuff already in boost.

Btw the reason for operator bool is to allow:

if (file_finder finder("*.dat"))
{
     file_finder::iterator i = finder.begin(); 
     do
         process_file(*i);
     while (++i != finder.end();
}
else
    throw no_files_found;
