# easy to see just 2 statements
if (...) {

if (...) {

# harder to see only 2 statements

if (...) {

I cuddle my elses as well, and I don’t think it hurts readability at all (actually, I think it helps to have all elses and elsifs preceeded by a close brace) but there *is* something you can put between an if and an else: comments.

### Do such and such in some case
if ($foo eq $bar) {
…
}
### Do something else in another case
elsif ($bar eq $baz) {
…
}
### Catch other cases
else {
…
}

I don't think that readability is hurt one bit, it's easy to read: } else { And it makes more sense to me. An "else" can't exist without an "if" - and you can't put anything in between the two. If you don't cuddle the else, it looks like a statement in its own right, meaning you could do something like: if(something) { } die "here"; else { } As you all know, this is syntactically incorrect. Hence why "} else {" makes more sense. I much prefer cuddled.

if(something) {

die “here”;
else {

As you all know, this is syntactically incorrect. Hence why “} else {” makes more sense.
