IME (used Perl daily at work for years) not much. If you need something more robust or sophisticated than sh(1)& cie, it's best to head up to a statically typed language instead -- I tend to favor go, in part because of the cross-compilable fat binary thing. The lack of static typing is especially annoying when things are getting beefy enough to consider moving away from sh(1). For prototyping, if you know Perl already, why not; but even there, I personally reach out to sh(1) & friends instead.
