   Hi,

 User of the Switch package, I noticed a strange behavior with very
 simple regexps.

 When I try to run this simple program:

    #!/usr/bin/perl -w
    use strict;
    use Switch;
    switch ('foo') {
       case /^bar\s+\S+/ {
           # +
       }
    }
 (please note the comment)
 ... I get:
    syntax error at ./buggy.pl line 7, near "}continue"
    syntax error at ./buggy.pl line 8, near "}"
    Execution of ./buggy.pl aborted due to compilation errors.

 Removing the comment stops the barking.

 This does not happen in comments only, but in any piece of text with
 some "+"ses here and there.

 Sorry, I'd like to provide a patch or to point the culprit, but this
 is beyond my skills.

   Regards,

[Please do not change anything below this line]
