As requested here is the salient output from perl -V with Switch 2.01 and Text::Balaced 1.83:

The error message is slightly different but it amounts to the same thing:

    String found where operator expected at switch.pl line 9, near "ca
+se 'y'"
        (Do you need to predeclare case?)
    syntax error at switch.pl line 8, near "){"
    Execution of switch.pl aborted due to compilation errors.

Update: I also checked this on Windows and got the same results. At first I couldn't find STDERR but I eventually found it redirected to a Word document in a folder called "My Favourite Errors". I also noticed that the Paper Clip had become more agitated than usual:

    [Clip]: Cleep!! Cleep cleep cleep cleep!
    [John]: What is it Clip? What is it girl?
    [Clip]: Cleep! Cleep cleep cleep. Cleep cleep!
    [John]: What! Uninitialised variable stuck under a tractor?
    [Clip]: Cleep!
