Re^3: How to get a true canonical path

[haukex]

Nitpicks: File::Spec::Functions doesn't need to be loaded since it isn't being used, and since File::Spec is already being used, I'd recommend File::Spec->curdir and File::Spec->updir instead of "." and "..".

But as was already mentioned in this thread, such logical cleanups have potentially major caveats. Going out to the filesystem with Cwd's abs_path and related is generally better.
