Hi All, Lately I have started to use a new idiom when I want to do "switch"-like things. I was wondering if this idiom might have some undesirable side effects that I might not know about. Such as a lot of overhead or a big performance hit. What I used to do was something like this: 
my $test = $foo->bar();
if($test=~/good.*food/){
  # do something
}
elsif($test eq "tacos"){
  # do something else
}
elsif(ref($test) eq "Burrito"){
  # do something else
}
else{
  # print out some message
}

What I have started doing is something like below. For me it is easier to read. 
for($foo->bar()){
  if(/good.*food/){
    # do something
  }
  elsif($_ eq "tacos"){
    # do something else
  }
  elsif(ref eq "Burrito"){
    # do something else
  }
  else{
    # print out some message
  }
}

Thoughts?
