Right, I wasn't advocating for Switch itself, so much as supporting the
syntactic structure of switch that can be found in many programming languages. 
Looks like Perl does this most stably (right now) with this structure:

for ($var) {
  when (/^abc/) { $abc = 1 }
  when (/^def/) { $def = 1 }
  when (/^xyz/) { $xyz = 1 }
  default { $nothing = 1 }
}

and, "highly experimentally", with

given ($var) {
  when (/^abc/) { $abc = 1 }
  when (/^def/) { $def = 1 }
  when (/^xyz/) { $xyz = 1 }
  default { $nothing = 1 }
}

While I'm sure using given would in most cases be safe, it could very well
introduce a difficult-to-trace problem for a non-typical install (where a
different Perl version could have snuck in).  I'm probably being overly
paranoid, but that's what a QAM is for!
