Since you asked... The following is much more readable to me than your
example.  That is why I wouldn't throw in all the extra space and  
parens.
Note, I didn't get rid of *all* the parens that Ruby would allow me to,
just some of them.  I doubt the extra parsing time introduced by the  
spacing
and parens would be problematic but the extra bugs introduced by  
having to
match all the extra parens would probably kill my productivity.

def print_dir(path)
   Dir.foreach(path) do |file_name|
       if File.ftype(file_name) == 'directory'
         print "[dir] #{file_name}\n"
       else
         print "      #{file_name}\n"
       end
   end
end
print_dir '.'
