IMO not following symlinks by default is safer. If you follow symlinks by default then everyone has the following issues: 1. Crossing filesystems (including onto network filesystems); 2. Recursive directory structures (symlink to a parent directory); 3. Symlinks to non-existent files/directories; 4. Symlink to an absolutely huge directory somewhere else (very annoying if you just wanted to do a directory sizer ...). If follow_symlinks=False by default, only those who opt-in have to deal with the above. Tim Delaney
