canonpath in File::Spec seems to do the trick.

Did you try it out?

#!/usr/bin/perl

use File::Spec;

print File::Spec->canonpath("foo/../bar/../baz/")."\n";

[download]

Output:

foo/../bar/../baz

I guess not. Did you read the docs? Quote:

Note that this does *not* collapse x/../y sections into y. This is by design.
I guess not.

All dogma is stupid.
