Not really. I vaguely remember trying out PDL and not getting very far. I was pretty comfortable writing C back then, so any time I'd run into performance issues in Perl, I'd usually just switch to C. Getting PDL working properly was painful enough that it didn't really seem worth spending a lot of time on when I could just write a small C program, especially for commandline data pipeline type situations. Once I started hitting projects with requirements for interactive GUIs though, keeping everything in the same language becomes more valuable and Python had the better complete package.
