IMPORTANT: RULE CLARIFICATION AND TEST ALIAS

I'd like to clarify a few of the rules and also use this opportunity to give you a test alias:

Code:
alias test_palicount {

  var %+ = scon 1 $(%test = %test, 0), %i = 1, %test, %time, %tot, %fail

  %+ jaytea 0
  %+ a 0

  echo 3 -eag Starting test:
  %time = $ticks

  while ($gettok(%test, %i, 32) != $null) {
    var %in = $v1, %out = $gettok(%test, $calc(1 + %i), 32)
    if ($palicount(%in) != %out) {
      echo 4 -ag Failed on $!palicount( $+ %in $+ ) (returned $v1 instead of %out $+ )
      inc %fail
    }
    inc %tot
    inc %i 2  
  }
  %time = $calc($ticks - %time)

  echo $iif(%fail, 4 -eag Failed. Only passed, 3 -eag Success! Passed) $calc(%tot - %fail) out of %tot tests in %time $+ ms

}


Just load and use /test_palicount to test out your alias

Now, rules.. some of you have made some good points and raised interesting questions so I'll attempt to clarify them all here:

1. Code will be tested on mIRC 7.52 (thanks Ouims :P)

2. COM: let us now say COM is now entirely disallowed. The rule in my post comes from a time when various scripters were learning and playing around with COM objects, and so I wanted to grant them the freedom to pursue methods that were almost certainly not going to be conducive to winning.

3. {} Braces: please include the final trailing brace. It's only 1 byte, everyone knows the trick by now, and I'll be adding it to your code if you omit it :P

4. Identifier warning will be disabled. Go nuts :P

I think that's it, but stay tuned to this topic in case there are any further updates. Have fun!
