The problem is that Switch.pm is a source filter, which is effectively
an extra level of processing before compilation.
Personally, I wouldn't use a source filter for anything I cared about.
The docs for Switch state:

This:
if ($op == 0) {}
elsif ($op == 1) {}
elsif ($op == 2) {}
elsif ($op == 3) {}
elsif ($op == 4) {}
elsif ($op == 5) {}
is faster than this:
use Switch;
switch ($op) {
case 0 { last }
case 1 { last }
case 2 { last }
case 3 { last }
case 4 { last }
case 5 { last }
}

Are you saying that 'if-elsif-else' is a compil
In addition, I've been playing around with the 'use diagnostics' feature in perl.
That's in addition to 'use warnings'. I don't recommend it for regular coding but
when stumped it may help.

The Advantage is you get to use the switch statement. The disadvantage is
your code will run extraordinarily slow because the Switch module uses a run time
Filter. In short: isn't an is-elsif-else statement enough??

Howdy.
Could anyone please tell me what's wrong with the following "program"?
I'll try.
The compiler gives errors in the switch statement.
Perl doesn't have a native switch statement, but it is included as a
module in 5.8+
Thx!!
