One thing I really like in Perl is the number of different operators... I find it's nicer to express things idiomatically instead of using lots of if-else branching. With that in mind I'm wondering if there's a way to test whether a variable has one of a set of possible values... something similar to SQL concept of "WHERE id IN (13,16,18)" So instead of writing: 
if ($myfruit eq "bananas" || $myfruit eq "apples" || $myfruit eq "oran
+ges"){
  print "I like $myfruit!";
}
else {
  print "I don't like $myfruit!";
}

I could write 
if ($myfruit in ("bananas","apples","oranges")){
  print "I like $myfruit!";
}
else {
  print "I don't like $myfruit!";
}

Any ideas? I know that typically hash keys are used for set comparisons, but it's less elegant because I'd have to create the hash just for the comparison.
